Technical Field
[0001] The present invention relates to a technology of, when a user selects and registers
one or more programs from among multiple demand response programs in order to participate
in a demand response event, presenting a demand response program suitable as a registration
target and information on a demand response measure in connection with it after evaluating
a realization possibility to a demand response of the user.
Background
[0002] In demand and supply of energies, such as electric power, gas, water, and heat, it
is required for a quantity demanded and a quantity supplied of energy to be in agreement.
Therefore, when an energy demand increases, the quantity supplied is made to increase
in connection with this. However, when it is predicted that the energy demand moves
closer to a maximum supply capacity or exceeds the maximum supply capacity, implementation
of demand response (hereinafter, the demand response event) of entrusting suppression
of the energy demand or restricting energy usage to a user (generally also called
a demand response) is carried out.
[0003] In order for the user to participate in the demand response event, in principle,
the user needs to perform registration to the demand response program in advance.
Generally, regarding the demand response program, one or more demand response programs
are presented from one or more demand response program presenters. Theses demand response
programs differ in the registration condition, respectively, and existence of these
multiple demand response programs enable the users of a variety of energy demand modes
to participate in the demand response event. The user participates in the demand response
event by selecting and registering a program that conforms to its own energy demand
mode from among the multiple demand response programs.
[0004] As a technology of selecting and registering a program that conforms to the user's
demand mode from among multiple existing programs in this way, there is a method of
Japanese Unexamined Patent Application Publication No.
2000-78747. In this publication, the method supports the user so that the user' own consumption
condition may be satisfied and the user can perform an optimal selection with a cheap
rate easily when the user selects a provider from among multiple electric power utilities
freely and makes a contract.
Summary
[0005] In a scene of receiving a supply service of energy, a user adopts a measure of making
cheapest an electricity rate that must be paid in order to secure required productivity,
and this can be realized with a technology of the above-mentioned prior art literature
1. On the other hand, in a framework of the demand response, the user adopts a measure
such that a bonus that is a consideration to suppressing consumption energy becomes
a highest amount. However, since an increase of the bonus and a reduction of the productivity
are in a strong correlation, it is desirable that the user maximizes the amount of
bonus, without spoiling the user's own productivity excessively. Moreover, depending
on a demand response program, a promised condition must be often applied at the time
of registration to the program, and if an applied amount of energy suppression cannot
be achieved by any chance, a penal regulation may be charged. Therefore, it is important
to secure in advance that the amount of energy suppression that is assumed is realizable.
However, in the framework of demand response, since a variety of demand response programs
exist and each of the demand response programs differs in conditions, such as a bonus
unit price, existence of penal regulations, a time zone of a demand response event,
and a computation method of an amount of suppression energy, it is not easy to select
a most suitable demand response program from among them. In addition, a judgment of
the measure for realizing the amount of suppression energy that is assumed is not
easy, either. Then, the object of the present invention is to, in a scene where the
user selects one or more programs from among multiple existing demand response programs
and registers them, make it possible to evaluate that the demand is an achievable
condition and after that to extract and present a program most suitable to a desire
of the user with a simple apparatus.
[0006] In order to achieve the above-mentioned object, in the present invention, registration
to the demand response program by a user is supported in a scene where the user selects
and registers a suitable program from among the multiple demand response programs
by: estimating an amount of suppression energy of the user from the user's past demand
history information based on a condition of each demand response program; further
making a determination as to existence of both a demand response measure as a physical
operation method of a load facility for satisfying an amount of estimation and a demand
response measure as a contrived behavior that does not depend on a special function
of an energy facility based on facility information that the user owns; in addition,
improving certainty of energy suppression of the user by the demand response measure
and by presenting an alternative means to the user; and after that, presenting the
demand response program that can conform to desired conditions acquired from the user
in advance. In this case, the desired conditions acquired from the user are a time
zone in which participation in the demand response event is possible and a value obtained
by quantifying an extent of energy that should be suppressed as compared with the
demand at a normal period when the demand response event is not activated, and using
these values is one mode of the present invention. Moreover, the certainty of energy
suppression means that multiple operation measures of a facility capable of realizing
the amount of suppression energy that is targeted exist and the user accepts the measure.
Others, i.e., a problem that the present application discloses and its solution means
become clear by a column of the best mode for carrying out the invention and drawings.
[0007] According to the present invention, in a scene where the user selects one or more
programs from among the existing multiple demand response programs and registers them,
it becomes possible to evaluate that the demand is an achievable condition and after
that to extract and present a program that is most suitable to the desire of the user.

Detailed Description
[0009] Hereinafter, embodiments of the present invention will be described taking electric
power as energy for example, with reference to drawings.
<Configuration example of embodiment>
[0010] Fig. 1 shows an embodiment (a demand plan management system) of the present invention.
The demand plan management system has a demand plan management apparatus 1302, a demand
response program management apparatus 1102, a user information management apparatus
1402, a demand information collection apparatus 1002, and a network 1001 that connects
these apparatuses.
[0011] A service provider A 1101 and a service provider B 1201 own and manage the demand
response program management apparatus 1102 for managing a demand response program.
In order to select a suitable program from among the demand response programs that
the service provider A 1101 and the service provider B 1201 make public, a user 1401
entrusts a processing to select the demand response program to the demand plan management
apparatus 1302 that a service provider X 1301 owns and manages through the user information
management apparatus 1402. Based on the registration condition of each program acquired
from the demand response program management apparatus 1102 through the network 1001
and the information of the user 1401, such as demand history information, facility
information, and the building information, that were acquired from the user information
management apparatus 1402 through a network 1011, the user information management
apparatus 1402 synthetically evaluates productivity, the amount of bonus, and executability,
and subsequently presents a suitable demand response program to the user information
management apparatus 1402. Here, the demand history information is time series data
of the consumption electric power measured with arbitrary time intervals in the demand
information collection apparatus 1002. Here, the demand information collection apparatus
1002 refers to an apparatus for measuring the amount of energy used (electric power,
gas, water, heat quantity, etc.), such as a so-called smart meter. Moreover, a word
"program" used in this embodiment is used as a term indicating a classification (a
menu) of the demand response. That is, it is not a term that indicates a computer
program.
[0012] Fig. 2 shows details of each apparatus. The demand plan management apparatus 1302
is an apparatus that evaluates the productivity, the amount of bonus, and effectiveness
of the user, and extracts and presents the demand response program suitable for the
user 1401 based on registration conditions of multiple demand response programs and
information of a demand history, a load facility, a building, etc. of the user. The
demand response program management apparatus 1102 is an apparatus for managing the
demand response program that holds the registration conditions, such as, a unit price
of bonus of the demand response program, an activation time zone of a demand response
event, a computation method of reference electric power, an amount of minimum suppression
electric power required when being registered, existence of penal regulations and
their system, and a facility condition that is required to hold information of the
registration conditions when being in participation. The user information management
apparatus 1402 is an apparatus for managing: the demand history information such that
the user's consumption electric power is recorded in time series; the facility information
of load facilities of an air conditioner, illumination, etc. that the user 1401 owns,
of supply facilities of a storage battery, a power generator, etc. and of a facility
for controlling these facilities, and the like; and the building information of a
layout plan of rooms and a physical arrangement of facilities, an electric power system,
a control system, etc. The demand information collection apparatus 1002 is an apparatus
that generates and transmits the demand information by measuring the consumption electric
power of the user 1401 with arbitrary time intervals and adding date and time information
to it.
[0013] Next, hardware and a functional configuration of each apparatus will be explained.
The demand plan management apparatus 1302 is an apparatus whose main purpose is to
extract a program suitable as the demand response program that the user 1401 registers
from the registration condition of the demand response program, and the demand history
information, the facility information, and the building information of the user, and
present it with the measure information for satisfying the conditions when the user
1401 makes registration. Explaining it as an example with a minimum configuration,
it is an information processing device, such as a personal computer, a server computer,
and a hand-held computer, that is comprised of a CPU 2301, input devices 2302 of a
key board, a mouse, etc., output devices 2303 of a display, a printer, etc., a communication
device 2304 of a wireless LAN, a cable LAN, etc., and a storage apparatus 2305 of
memory, a hard disk drive, etc.
[0014] The storage apparatus 2305 stores at least the following computer programs. (1) A
registration candidate program extraction program 2306 (a registration candidate program
extraction part) for acquiring a conforming demand response program from the demand
response program management apparatus 1102 based on desired preconditions, such as
a time zone in which participation in the demand response is possible, existence of
penal regulations, or whether a supply facility of the storage battery, the power
generator, etc. is used or not. (2) A suppression electric power estimation program
2307 (a suppression electric power estimation part) for estimating amounts of the
maximum consumption electric power expected for each demand response program, of the
reference electric power, and of the suppression electric power that is their difference
using the demand history information acquired from the user management apparatus 1402
based on the calculation system of the reference electric power described in the demand
response program that the registration candidate program extraction part 2306 acquired
and a condition of the demand response event time zone. (3) A demand response balance
computation program 2308 (a demand response balance computation part) that computes
a received amount of bonus that is expected from bonus unit price information of each
demand response program, additionally computes also an expenditure that may arise
from participating in the demand response event, and computes an amount of difference
thereof as a demand response balance. (4) A demand response measure generation program
2309 (a demand response measure generation part) for generating a measure of an electric
power facility operation at the time of demand response event activation and a measure
as a contrived action not depending on the electric power facility from the estimate
value of the maximum consumption electric power outputted by a suppression electric
power estimation part 2307 based on the facility information and the building information
that were acquired from the user information management apparatus 1402. (5) An incident
information storage means 2312 for storing a factor of bringing about a phenomenon
in which the consumption electric power largely exceeds the estimate value thereof
at the time of the demand response event activation and an incident management program
2310 (an incident management part) for generating an alternative measure at the time
of becoming so. (6) A registration program selection indication program 2311 (a registration
program selection indication part) for extracting and presenting a suitable demand
response program that the user 1401 should register based on an amount of demand response
balance for each program computed by the demand response balance computation part
2308.
[0015] The demand response program management apparatus 1102 is an apparatus whose main
purpose is to manage information of the demand response program, and is the same information
processing device as the demand plan management apparatus in hardware.
[0016] A storage apparatus 2105 that the demand response program management apparatus has
includes a demand response program information storage means 2106 for recording the
registration conditions to the program, such as a unit price of bonus, the activation
time zone of the demand response event, a computation method of the reference electric
power, the amount of the minimum suppression electric power required when registering,
existence of penal regulations and its system, and conditions of a facility that needs
to be owned when participating for each demand response program, and a computer program
2107 (a demand response program management part) for managing the demand response
program for performing registration, search, update, and deletion on the storage means
2106.
[0017] The user information management apparatus 1402 is an apparatus whose main purpose
is to present information of the user, such as the demand history information, the
facility information, and the building information of the user, and is the same information
processing device as the demand plan management apparatus in hardware.
[0018] A storage apparatus 2405 that the user information management apparatus has stores
at least three databases and three computer programs. First, the storage apparatus
2405 has the followings as the databases: (1) a facility information storage means
2406 for holding the facility information, such as load facilities of air conditioners,
illumination, etc., supply facilities of the storage battery, the power generator,
etc., and control facilities for controlling these loads facilities and supply facilities;
(2) a building information storage means 2408 for holding information related to a
configuration of the whole building, such as a floor plan of rooms that the user manages,
a physical arrangement of facilities in a room, electric power systems and control
systems of the facilities, and further materials and a location of the building; and
(3) a demand history information storage means 2410 for holding a value of the user's
consumption electric power as time series data.
[0019] Next, as computer programs, (1) a facility information management program 2407 (a
facility information management part) that performs registration, search, update,
and deletion on the storage means 2406, (2) a building information management program
2409 (a building information management part) that performs registration, search,
update, and deletion on the storage means 2408, and (3) a demand history management
program 2411 (a demand history management part) that performs registration, search,
update, and deletion on the storage means 2406 are provided.
[0020] The demand information collection apparatus 1002 is an apparatus whose main purpose
is to measure the consumption electric power of the user and transmit demand information,
and has a consumption electric power measurement part 2005 for measuring the consumption
electric power of the user 1401 with arbitrary time intervals and a demand information
transmission part 2006 for transmitting consumption electric power information measured
by the measurement part 2005 with time and date added thereon to the user information
management apparatus 1402. Although in this embodiment, an example where the user
itself manages the user information management apparatus 1402 is shown, a service
provider X 1301, a service provider A 1101, or a service provider B 1201 may perform
operation management, or an electric power utility may perform the operation management,
for example. Next, a general outline of a processing for acquiring the effect by the
present invention will be explained using Fig. 3.
[0021] First, at step S301, based on information of the desired preconditions to participation
in the demand response event acquired from the user, for example, a time zone in which
participation in an event is possible, existence of penal regulations, or whether
the supply facilities of the storage battery, the power generator, etc. are used,
a conforming demand response program is acquired from the demand response program
information storage means 2106. The registration candidate program extraction part
2306 performs this processing. The demand response program information storage means
2106 that is a target of an acquisition processing at this time does not need to be
limited to what a certain specific service provider manages. Next, at step S302, when
the registration candidate program extraction part 2306 acquires the multiple demand
response programs, one of them is selected, by using the demand history information
of the user 1401 that is acquired from the demand history information storage means
2410 in parallel based on a computation method of the event activation time zone and
the reference electric power of the selected demand response program, an estimate
value of the maximum consumption electric power, an estimate value of the reference
electric power, and an estimate value of the suppression electric power computed as
their difference during activation of the demand response event are computed. The
demand history information is, for example, information obtained by measuring the
demand electric power represented with a unit of kW every 30 minutes with time and
data information added and recorded thereon. The suppression electric power estimation
part 2307 performs this processing.
[0022] After that, at step S303, the amount of bonus according to a bonus unit price of
the demand response program is computed based on the estimate value of the suppression
electric power computed at S302, further, expenditures that arise from participating
in the demand response event, for example, an expenditure of a fuel charge for operating
the power generator, are also computed, and a difference of the amount of bonus and
an amount of expenditures is computed as the demand response balance. The demand response
balance computation part 2308 performs this processing. Moreover, at step S304, based
on the facility information of the user 1401 acquired from the facility information
storage means 2406, operation measure information of a facility in which the estimate
value of the peak consumption electric power computed at the S302 is set as a constraint
upper limit, for example, a temperature setting range of an air conditioner, the number
of air conditioners that can be activated, etc. and measure information regarding
a behavior of the user, for example, specification of air conditioning outdoor unit
on which chilled water is splashed and specification of windows kept open, etc. are
generated. The demand response measure generation part 2309 performs this processing.
[0023] Incidentally, although it is considered in this embodiment that step S303 and step
S304 have no dependency in a processing order and are put into a parallel processing,
they may be processed one by one sequentially.
[0024] The processings of the above-mentioned steps S302, S303, and S304 are performed repeatedly
by the number of registration candidate programs extracted at step S301. After that,
at step S305, phenomenon information that can hinder realization of electric power
suppression that is a target and measure information for its countermeasure are generated.
For example, to phenomenon information that it becomes extremely seriously intense
hot in the demand response event activation day, measure information, including halting
some businesses, making a day no-business day temporarily, etc. is generated as a
measure for its countermeasure. The incident management part 2310 performs this processing.
[0025] Finally, at step S306, based on the amount of demand response balance computed at
step S303, the demand response program suitable for the user 1401 is extracted, and
is presented to the user 1401. Moreover, information of the amount of demand response
balance computed at step S303, demand response measure information generated at step
S304, and alternative measure information generated at step S305 are presented simultaneously
with it. The above is an explanation of an outline of the whole processing of the
present invention. As a utilization mode of the present invention, it completes by
the user's decision making after information presentation to the user at step S306.
For example, if the user made a decision that the user wished to alter a desired condition
and perform the selection again, steps S301 to S306 will be repeatedly performed upon
an input of desired condition information from the user after the alteration.
[0026] Below, details of a processing in each of processing parts that process step S301
to S306 will be explained.
[0027] Details of the processing of the registration candidate program extraction part 2306
will be explained using Fig. 4, Fig. 5, Fig. 6, and Fig. 7.
[0028] As explained in the processing of step S301, the registration candidate program extraction
part 2306 is a processing part whose main purpose is to extract the demand response
program of the registration candidate based on the desired preconditions acquired
from the user.
[0029] First, at step S401, all the demand response programs that coincide with the conditions
are acquired from the demand response program management apparatus 1102 by using the
user's desired preconditions as keys. For example, when the user transmits the precondition
information to the demand plan management apparatus 1302, an input transmission form
as shown in Fig. 5 may be used. In an example of Fig. 5, as the user's desired conditions,
a time zone in which participation in the demand response event possible is "13:00
to 16:00" (5001), penal regulation clause is "none" (5003), and a usable supply facility
at the time of the demand response event is "none" (5004). By the user pressing a
"search" button (5005), a processing of step S401 is started. The demand response
program information that becomes a search target is held in the demand response program
information storage means 2106 as table data, for example, as shown in Fig. 6. Here,
if based on the time zone (5001) in which participation is possible, the existence
(5003) of the penal regulation clause, and the usable supply facility (5004), a line
6003, a line 6004, a line 6005, and a line 6007 will be acquired as the demand response
program that coincides with the desire of the user 1401. Next, at step 402, a demand
response program list of registration candidates also including a combination of demand
response programs that can be registered simultaneously is created. For example, the
demand response program of a program name "P03" of the line 6003 and the demand response
program of the program name "P07" of the line 6007 have no possibility of event overlapping
because the event time zones at a time of the activation of the demand response event
are "13:00 to 14:00 (a start time to an end time)" and "14:00 to 15:00," respectively.
Therefore, the demand response programs of the program names "P03" and "P07" are one
of combinations of demand response programs that can be registered simultaneously.
Similarly, it is also possible for the demand response program of the program name
"P05" and the demand response program of the program name "P07" of the line 6005 to
be simultaneously registered." Finally, combinations of six patterns of the demand
response programs shown in Fig. 7 are extracted as registration candidate programs,
which are stored in the memory as a registration candidate program list at step S403,
and a processing in the registration candidate program extraction part is ended.
<One example of suppression electric power estimation processing>
[0030] Details of a processing of the suppression electric power estimation part 2307 will
be explained using Fig. 8, Fig. 9, and Fig. 10.
[0031] Fig. 8 shows a processing flow. First, at step S801, one pair of combination whose
processing in this processing part has not been done is extracted from the registration
candidate program list stored in the memory at step S403. For example, the demand
response program of the program name "P03" shown in a line 7001 is extracted from
the registration candidate program list shown in Fig. 7. Next, at step S802, the calculation
method of the reference electric power of the extracted demand response program is
extracted. For example, from the line 6003 of Fig. 6, the computation method of the
reference electric power of the demand response program "P03" is one that finds the
maximum consumption electric power in a month. Subsequently, at step S803, a distribution
of the reference electric power fbase is computed from the demand history stored in
a demand history storage means 2401 based on the extracted calculation method of the
reference electric power. Next, at step S804, a demand response event period of the
demand response program extracted at step S801 is extracted. For example, a start
time and an end time of the demand response program "P03" are "13:00" and "14:00,"
respectively, from the line 6003 of Fig. 6. Therefore, "13:00 to 16:00" is extracted
as the demand response event period. Subsequently, at step S805, all the demand history
information corresponding to the demand response event period extracted at step S804
are acquired from a demand history information storage means 2410, and a consumption
electric power distribution fnormal at a normal period during the demand response
event period is computed based on the acquired information.
[0032] On the other hand, at step S806, all the demand history information of holidays are
extracted from the demand history information storage means 2410 and a consumption
electric power distribution fproMin is computed. Moreover, at step S807, from all
the demand history information stored in the demand history information storage means
2410, the demand histories in top 1% in descending order of numerical value are extracted
and a consumption electric power distribution fproMax is computed. Since S802, S804,
S806, and S807 do not have a dependency at the time of processing start, it does not
matter if a parallel processing is performed. Next, at step S810, parameters for computing
the consumption electric power distribution at an arbitrary value of the productivity
are estimated, considering the consumption electric power distribution fproMin generated
at S806 as a distribution when the productivity is zero, the consumption electric
power distribution fproMax generated at S807 as a distribution when the productivity
is unity, and the consumption electric power distribution fnormal generated at S80
as a distribution when the productivity is 0.5. One example of this processing will
be explained using Fig. 9. One examples of the consumption electric power distribution
fproMax computed at step S807, the consumption electric power distribution fnormal
computed at step S805, and the consumption electric power distribution fproMin computed
at step S806 are shown in 9001, 9002, and 9003 in Fig. 9, respectively, with the consumption
electric power on a transverse axis and the probability on a vertical axis. For example,
9001 shows results that at step S807, an average value and a standard deviation are
computed to be 251 kW and 10.3, respectively, and the consumption electric power distribution
fproMax is computed in a normal distribution based on the average value and the standard
deviation with the consumption electric power (kW) on a transverse axis. Similarly,
at step S805 and step S806, it is computed that the average values are 186 kW and
23.3 kW, and the standard deviations are 34.6 and 0.588, respectively. An average
value of 251 kW computed at step S807, an average value of 186 kW computed at step
S805, and an average value of 23.3 kW computed at step S806 when the productivity
is assumed to be unity, when the productivity is assumed to be 0.5, and when the productivity
is assumed to be zero, respectively, are plotted in a diagram with the productivity
on a transverse axis and the average value on a vertical axis are shown in 9004. Fitting
these three points with a binomial expression, a curve is calculated as "y = -0.00194x2
+ 4.2171x + 23.269 (Formula 1)" denoting the productivity as x and an average value
of the consumption electric power as y.
[0033] Similarly, regarding the standard deviation, 9005 shows points plotted in a diagram
with the productivity on a transverse axis and the standard deviation on a vertical
deviation, and fitting these three points with a binomial expression, a curve is calculated
as "y = -0.00116x
2 + 1.2618x + 0.5883 (Formula 2)" denoting the productivity as x and the standard deviation
as y. The above is one example of the processing at step S810, in which parameters
of the consumption electric power distribution at an arbitrary productivity are estimated
from the consumption electric power distribution fproMax, the consumption electric
power distribution fnormal, and the consumption electric power distribution fproMin
that are computed at steps S807, S805, and S806, respectively. Next, at step S811,
a presumed distribution of consumption electric power fcons at a desired productivity
of the user 1401 is computed from information on productivity at the time of demand
response event that has been acquired in advance from the user as the desired precondition.
For example, as shown in 5002 of Fig. 5, the user desires "slight suppression" as
the productivity at the time of demand event activation. This is equivalent to a productivity
of 30% when the productivity at the normal period is assumed to be 50% as shown also
in 5002. Therefore, assuming the productivity x as 0.3 from the formula (Formula 1)
of the average value of the consumption electric power to the productivity computed
at step S810, 132 kW is computed as the average value of the consumption electric
power. Similarly, a standard deviation of 28.0 is computed from a formula of standard
deviation (Formula 2) to the productivity. Fig. 10 shows a result of the presumed
distribution of the consumption electric power at a productivity of 30 % that is a
desire of the user as a normal distribution based on the above-mentioned average value
and standard deviation computed with the consumption electric power on a transverse
axis and the probability on a vertical axis. Next, at step S813, a presumed distribution
freduct of the suppression electric power is computed from the reference electric
power distribution fbase computed at step S803 and the consumption electric power
distribution fcons computed at step S803. Specifically, for example, each probability
of each of n reference electric powers of 0 (kW) to n (kW) is computed based on the
reference electric power distribution fbase computed at step S803, and n-dimension
discrete vector b = [b(n), ..., b(0)] is generated as an arrangement. Next, each probability
of each of k consumption electric powers of 0 (kW) to k (kW) based on the consumption
electric power distribution fcons computed at step S811, and k-dimension discrete
vector p = [p(k), ..., p(0)]T is generated as an arrangement. Then, an inner product
p ● b of the vector p and the vector b is calculated to compute a kxn matrix. This
matrix is the suppression electric power distribution freduct. For example, a value
of an element in the first column of the first row of this matrix means a probability
that the suppression electric power that is a difference becomes n-k (kW) in which
the reference electric power becomes n (kW) and the consumption electric power becomes
k (kW). Finally, at step S815, the expected value and standard deviation of the suppression
electric power are computed from the computed suppression electric power distribution
freduct. By the above processing, the suppression electric power in each demand response
program at a productivity that the user desires is estimated.
[0034] Although in this embodiment, a normal distribution was used as the consumption electric
power distribution, for example, another distribution that conforms to a data tendency
of the demand information, such as a log normal distribution, may be used. Moreover,
although also regarding the calculation method of the parameters of the distribution,
the average value and the standard deviation were used by a simple computational operation
based on the demand history in this embodiment, a statistical method, such as maximum
likelihood estimation, may be used. Next, details of a processing of the demand response
balance computation part 2308 will be explained. First, a receivable amount of bonus
to participation in the demand response event is computed. For example, it may be
all right that expected value information of the suppression electric power that was
computed at step S815 and was recorded in the memory at step S816 is called and a
value obtained by multiplying it by the bonus unit price of the demand response program
is computed as the receivable amount of bonus. Moreover, for example, it may be all
right that the suppression electric power distribution freduct expressed as a kxn
matrix that was computed at step S813 and was stored in the memory at step S814 is
called, the bonus unit price of the demand response program is multiplied to the suppression
electric power computed for each element of the suppression electric power distribution
freduct, and after that an expected value of the amount of bonus and its standard
deviation are computed.
[0035] Next, an expenditure that may occur in order to participate in the demand response
event is computed. For example, when the user 1401 owns a private power generator
and makes it the desired condition to use the private power generator, a fuel charge
for making the private power generator operate during the demand response event period
is computed as an expenditure. Moreover, when using the storage battery, an electric
usage fee for inputting predetermined electric energy into the storage battery is
computed. A difference between the computed receivable amount of bonus and the amount
of expenditures that can occur is computed as the amount of demand response balance.
[0036] Moreover, when penal regulation clause exists in the conditions of the demand response
program, a penalty that can occur may be computed. For example, in the case where
a content of the penal regulation clause is a content that a penalty of 300 yen is
paid each time the suppression electric power for each shot measured by setting 30
minutes to one shot at the time of the demand response event lowers by 5 (kW) to the
suppression electric power that was applied in advance at the time of registration
to the demand response program, a penalty when the suppression electric power decreases
by multiple of 5 (kW) may be computed on the basis of the expected value of the suppression
electric power computed at step S815.
<One example of demand response measure>
[0037] Using Fig. 11 and Fig. 12, details of a processing of the demand response measure
generation part 2309 will be explained.
[0038] Fig. 11 shows one example of a processing of generating an operable range of an electric
power load facility that the user 1401 owns as one of the demand response measures.
First, at step S1101, an expected value of the consumption electric power distribution
fproMin at a productivity of zero computed at step S809 and an expected value of the
consumption electric power computed at S812 are acquired from respective pieces of
the memory, and a difference thereof is computed as a consumable electric power. For
example, since an expected value of the consumption electric power distribution at
a productivity of zero is 23.3 (kW) from 9003 of Fig. 9 and an expected value of the
consumption electric power at a productivity of 0.3 is 132 (kW) from Fig. 10, a consumable
electric power at a productivity of 0.3 is computed as 99.8 (kW). Next, at step S1102,
an operation range of the electric power load facility that defines an electric power
computed at step S1101 as a constraint condition is generated based on electric power
load facility information of the user 1401 held in a facility storage means 2406.
For example, Fig. 12 shows one example of the electric power load facility information
of the user 1401 held in the facility storage means 2406. From Fig. 12, the user 1401
owns total 16 facilities of facility ID's "A001" to "A016" as air conditioning facilities,
and a sum total of their consumption electric powers is 160 (kW). Moreover, as lighting
facilities, it owns a total of 400 facilities of facility ID "L001" to "L400," and
a sum total of their consumption electric powers is 40 (kW). When the consumable electric
power of 99.8 (kW) computed at step S1101 as a specific example is considered as the
constraint condition, facility operation range information, for example, that "the
operable facilities are total nine air conditioning facilities and total 98 lighting
facilities" is generated as the operation range of the electric power load facility
of the user 1401. Moreover, as another measure, facility operation range information
that "operable electric power load facilities are total five air conditioning facilities
and total 400 lighting facilities" may be generated. Moreover, regarding facility
operable range information, all the operation ranges may be calculated and generated,
or the processing may be ended at a stage where the number of generations reaches
the number of cases decided in advance. Moreover, when the desired precondition about
the operation range of a facility has been acquired in advance from the user, the
condition may be added as a constraint condition. For example, when a desired precondition
that "operable air conditioning facilities is six or more" has been acquired from
the user in advance, taking the consumable electric power of 99.8 (kW) as an example,
regarding the generated facility operable range information, information that "the
operable electric power load facilities are total six air conditioning facilities
and total 398 lighting facilities, and inoperable electric power load facilities are
total 10 air conditioning facilities and total 100 lighting facilities" may be generated
and information that "the operable electric power load facilities are total seven
air conditioning facilities and total 298 lighting facilities, and the inoperable
electric power load facilities are total nine air conditioning facilities and total
200 lighting facilities" may be generated. Moreover, the facility operable range information
may be generated based on the priority of electric power supply set up in advance
for each facility. For example, values of 1 to 5 are recorded in a column of the "priority"
of an electric power load facility table shown in Fig. 12 in ascending order of the
priority of the electric power supply. In this example, since the priority of the
air conditioning facility of a facility ID "A004" shown in a line 1403 is "5," it
is incorporated first as one of the operable power load facilities. Taking the consumable
electric power of 99.8 (kW) as an example, incorporation of the facility ID "A004"
as an operable electric power load facility makes a residual consumable electric power
become 89.8 (kW). Subsequently, since a facility of a high priority next to this is
the air conditioning facility of a facility ID "A003", the facility is incorporated
as one of the operable electric power load facilities and the residual consumable
electric power becomes 79.8 (kW). After this, similarly, the facility operation range
information is generated by repeating the operation until an operable facility ceases
from existence to the consumable electric power. Moreover, it may be all right that
more concrete information on the user's behavior is generated as the demand response
measure information and information on the building that the user 1401 owns is used
as the facility information for generating the behavior information. As information
about the building, one example is shown in Fig. 13 and Fig. 14. 1301 of Fig. 13 shows
a floor plan of one floor in the building of the user 1401, for example, the user
1401 has attached names, such as a conference room A, a conference room B, and an
office, to respective locations of the floor. On the other hand, 1302 of Fig. 13 shows
one example for managing each location of the floor by a location ID, and Fig. 14
shows one example of managing this information as table information. For example,
a location called the conference room A is represented by total nine pieces of ID
information of six pieces of ID information, location ID's "P101," "P102," "P103,"
"P201," "P202," and "P203," plus "P301," "P302," and "P303" from 1401, 1402, 1403,
1404, 1405, and 1406 of Fig. 14. However, for simplification of expression of the
figure, representations of "P301," "P302," and "P303" are omitted in Fig. 14. Here,
for example, suppose that it became clear for a lighting facility of a facility ID
"L001" shown in 1204 of Fig. 12 to be unable to operate as a result of a processing
of generating the facility operable range information. Since the facility ID "L001"
is installed in the conference room A that has a location ID "P101" from 1401 of the
location information table of Fig. 14, information that "a lighting facility "L001"
installed in the location "P101" of the conference room A is cut off" is generated
as the demand response measure information.
[0039] The above is one example of a concrete processing in the demand response measure
generation part 2309. The demand response measure information generated finally by
the generation part only needs to be an expression that people can understand easily,
and therefore character information, image information, speech information, etc. will
do.
<One example of incident and action means>
[0040] A concrete example of a processing in the incident management part 2310 will be explained
using Fig. 15. Fig. 15 shows one example of information currently held in an incident
information storage means 2312, and 1501 among them shows one example of incident
information that is factor information that can hinder realization of the amount of
suppression electric power estimated in the suppression electric power estimation
part 2307.
[0041] For example, a line 1504 records the followings as one piece of the incident information:
as one of direct factors that may hinder realization of the amount of suppression
electric power, there is a factor that the reference electric power calculated in
a day when the demand response event actually activates become less than the reference
electric power estimated in the suppression electric power estimation part 2307; and
furthermore, as one of indirect factors of the direct factor, there is a factor that
the maximum value in a month of the event activation month by the computation method
of the reference electric power becomes less than an estimate value estimated by the
suppression electric power estimation part 2307. On the other hand, 1502 of Fig. 15
shows one example of action measure information to a sudden phenomenon that is other
than targets of the generated information in the demand response measure generation
part 2309. For example, on the line 1505, as one of the countermeasures to a certain
event, an action measure that before a time when the demand response event is activated,
a room temperature inside a room is kept in a state lower than at the normal period
using the air conditioning facility is recorded. The incident information of 1501
and the action measure information of 1502 are associated with each other by a countermeasure
ID, for example, a countermeasure to a phenomenon ID "I01" of the line 1504 described
above is related to a countermeasure of a countermeasure ID "CP04." Moreover, the
incident information has a dependency according to the user's category of business,
a building scale, etc., and this is shown in a user classification incident information
table shown in 1503 of Fig. 15 as one example. For example, a line 1506 means that
there are phenomenon ID's "I01" and "I02" as incidents that may occur to the user
of a different classification of office work as a classification. Using user classification
information acquired from the demand in advance as a key, a phenomenon ID of an incident
that may occur to the user 1401 is extracted from information of 1503. Based on the
phenomenon ID, the incident information is extracted from 1501, and the action measure
information is further extracted from 1502. The user classification information may
be simultaneously acquired when acquiring the user's desired preconditions, or may
be acquired in advance in paper.
[0042] Moreover, in the combination of two or more registration candidate programs, although
there is a case where the action measure to the incident of one registration candidate
program may bring about an incident of the other program, at this time, the incident
and action measure to the program in which a penal regulation code is provided are
presented preferentially. In the case where none of the programs has the penal regulation
code, the incident and action measure to a program whose amount of balance is larger
are presented preferentially. For example, although in the demand response program
list of Fig. 6, "P08" of 6003 and the "P03" of 6008 overlap each other in a start
time and in an end time, there is no overlap in a computation range of the suppression
electric power because of a computation method of the suppression electric power;
therefore, the two programs become registration candidate programs that can be registered
simultaneously. Here, for example, when the phenomenon ID "I01" described in 1501
of Fig. 15 is extracted as an incident of "P03," the countermeasure ID "CP04" is extracted
as its countermeasure, and this will make the suppression electric power of the program
"P08" decrease as a result. In this case, since in final balances of the both programs,
the "P03" is calculated to be larger, the above-described incident corresponding to
the "P03" and its countermeasure are presented preferentially, and then the incident
corresponding to the "P08" and its countermeasure are presented.
<One example of information presented to user>
[0043] One example of information generated in a registration program selection indication
part 2311 will be explained using Fig. 16 and Fig. 17.
[0044] First, Fig. 16 shows one example of a screen at the time of being presented to the
user, and 1601 in Fig. 16 shows combinations of the registration candidate programs
in descending order of the positive amount of balance based on the amount of demand
response balance computed for each combination of the registration candidate programs
in the demand response balance computation part 2308. For example, 1602 shows that
as a result of a processing of the demand response balance computation part 2308,
the demand response program that makes the amount of balance of the demand response
highest is "P04," and its amount of balance is 81,000 yen. Moreover, it also shows
that as a condition for receiving the amount of balance, the consumption electric
power needs to be adjusted so that the consumption electric power at the time of the
demand response event may become 132 (kW) and the reference electric power may become
186 (kW). A next combination of the registration candidate programs in descending
order of the positive amount of balance is a combination of the demand response programs
of "P05" and "P07" shown in 1603, and similarly with what was mentioned above, the
screen shows the amount of balance, the consumption electric power that needs to be
adjusted for it, and the reference electric power.
[0045] Next, Fig. 17 shows one example of information presented to the user as details of
each demand response program. In this example, 1701 shows a computation basis of the
amount of demand response balance computed in the demand response balance computation
part 2308, 1702 shows a computation basis of the suppression electric power computed
in the suppression electric power estimation part 2307, 1711 shows the demand response
measure information generated in the demand response measure generation part, and
1712 shows incident action measure information extracted in the incident management
part 2310. Moreover, 1704 shows an index value of the productivity among the desired
preconditions that were acquired in advance from the user shown in 5002 of Fig. 5,
and 1703 shows a meaning of the index value shown in 1704. For example, in this embodiment,
the user desires the productivity at the time of the demand response event to be "slight
suppression (30%)" from 5002 of Fig. 5, and this shows an index value, as shown by
1703, when a productivity of a non-business day is assumed to be 0%, a productivity
in a day when the consumption electric power is especially large is assumed to be
100%, and a productivity at the normal period in the demand response event time zone
that is a condition of the demand response program is assumed is 50%. Moreover, 1710
shows a computation basis of the suppression electric power as an image diagram, 1705
shows an estimate value of the reference electric power computed in the suppression
electric power estimation part 2307, 1706 shows an estimate value of the consumption
electric power computed similarly in the suppression electric power estimation part
2307, and 1707 shows an estimate value of the suppression electric power computed
in the suppression electric power estimation part 2307 as their difference, respectively.
Moreover, 1708 shows the expected value of the consumption electric power distribution
at the normal period fnormal computed in the suppression electric power estimation
part 2307, and 1709 shows a standard deviation of the fnormal. Detailed information
of the demand response program that takes Fig. 17 explained in the above as an example
is generated for every combination of the registration candidate programs. Moreover,
1604 of Fig. 16 shows the demand response program that it is desirable for the user
1401 to register and that does not however apply to the user's desired preconditions
acquired in advance. For example, in 1604, a demand response program of "P02" is presented
as the demand response program that it is desirable for the user 1401 to register.
From 6001 of Fig. 6, since in a program of "P0," the penal regulation clause "exists,"
in a processing in the registration candidate program extraction part 2306, it is
not recorded on the registration candidate program list. However, since there is a
private power generator among owned facilities of the user 1401 from a line 1205 of
Fig. 12 and a participation condition of "P02" designates "owning of private power
generator" from 6001 of Fig. 6, it may be presented as the demand response program
that it is desirable for the user 1401 to register.
[0046] The above processing enables the user to grasp the demand response program that the
user itself should register and to judge whether the demand response behavior is achievable
from information of the demand response program that should be registered, shown in
Fig. 16 as one example, computation reason information of the suppression electric
power, shown in Fig. 17 as one example, and information of a measure in order to achieve
the suppression electric power and of a measure when contingency occurs, and therefore
it becomes possible to make a decision as to whether registration to the demand response
program is to be performed. As described above, the embodiment of the present invention
was explained concretely, but the present invention is not limited to this and can
be variously modified within a range that does not deviate from its gist. For example,
although in the above-mentioned embodiment, the user's desired preconditions were
acquired at the time of an operation start of the present invention, a case where
there are no desired conditions may be all right. In that case, all the demand response
programs become registration candidate programs, and subsequent processings are performed.
Moreover, although in the above-mentioned embodiment, as an acquisition method of
the desired preconditions, it was assumed that it was done through a network, the
present invention is not limited to this; for example, acquisition through paper may
be all right. Moreover, regarding its acquisition term, information more detailed
than the information of this embodiment may be acquired. Moreover, although in the
above-mentioned embodiment, in order to acquire the demand response program, it was
assumed that the demand plan management apparatus acquired it each time from the demand
response program management apparatus, it causes no trouble that the demand plan management
apparatus has acquired it in advance, and in that case, a timing of acquisition can
be asynchronous. Moreover, although in the above-mentioned embodiment, when generating
the operation range of the facility, the number of operable sets is computed based
on specification information of the rated consumption electric power, a concept of
the facility operation range is not limited to this. For example, a range of preset
temperature of an air conditioner may be generated based on a heat load simulation,
and the number of necessary lighting facilities in operation and an illuminance adjustment
value of the lighting facility may be generated based on an illuminance simulation.
Moreover, information in time series may be generated, for example, an alteration
timing of the preset temperature of the air conditioner etc. may be generated, Moreover,
although in the above-mentioned embodiment, when generating the demand response measure
information, it was assumed that the operation range of the electric power facility
that the user managed was generated, the present invention is not limited to this,
for example, operation ranges of multiple buildings that the user manages and operation
ranges of multiple users that the user manages may be objects to be generated. Moreover,
although in the above-mentioned embodiment, it was assumed that the incident information
was being held in advance as fixed information, the present invention is not limited
to this, for example, the incident information acquired from other users by a questionnaire
etc. and its countermeasure information may be kept accumulated. Moreover, although
in the above-mentioned embodiment, regarding information to be presented to the user
in 1712 of Fig. 17, the example in which all the countermeasures acquired from 1501
and 1502 of Fig. 15 based on a user classification of the user 1401 were presented
was shown, it is not necessarily needed to present all the countermeasures. For example,
if it is understood that a future atmospheric temperature variation has a downward
trend from a weather forecast, a possibility of occurrence of the incident of the
phenomenon ID "I02" of 1501 of Fig. 15 is also low, and therefore countermeasures
of the countermeasure ID's "CP01" and "CP02" do not need to be presented to the user.
Moreover, in the above-mentioned embodiment, when presenting the user the demand response
program that should be registered, only a largeness/smallness of the amount of balance
at the time of participating in the demand response event was considered as a condition.
However, the present invention is not limited to this, for example, it does not matter
that the demand response programs are in descending order of the number of the generated
demand response measures. Moreover, the demand response program that should be registered
may be presented after considering a balance so that registration may not lean to
a specific demand response program by referring to a registration situation to the
demand response program of another user. Moreover, in an actual operation, a single
provider may operate and manage the demand plan management apparatus and the demand
response program management apparatus. For example, such an operation as follows is
also acceptable: an electric power utility or a third party public institution operates
and manages these apparatuses, a third party service provider performs generation
of the demand response program, and the service provider entrusts registration of
the provider's own demand response program to a provider that operates and manages
the demand response program management apparatus. Moreover, although in the above-mentioned
embodiment, the explanation was given taking electric power as energy for example,
the present invention is not limited to this and may be also applied to measurable
energies, such as gas, water, and heat.
[0047] According to this embodiment, by extracting and presenting the demand response program
that it is desirable for the user to register after evaluating realistic electric
power suppression of the user at the time of the demand response event, it is made
possible to support decision making of the user with a simple apparatus. For example,
as one example thereof, the decision making for the registration to the demand response
program of the user can be supported by estimating the suppression electric power
at an arbitrary productivity and the amount of balance brought about by participation
in the demand response event using the user's past electric power consumption history
based on a condition different in each demand response program, and presenting an
action measure in contingency from the user-owned facility information in addition
to a measure of realizing the suppression electric power.
