Abstract (en)
[origin: WO2014005642A1] The invention describes a method for monitoring an energy feed-in point (ESP) of an energy supply network (EVN), particularly in the low voltage range, a number of first and second nodes (K11, K12, K13, K2) being connected or connectable to the energy feed-in point, the respective nodes (K11, K12, K13, K2) being an energy producer, an energy consumer or a prosumer. In the method according to the invention, an actual current which represents the current consumption or current output is detected at the energy feed-in point (ESP) by a measuring and monitoring device. A piece of current information (SI) received from one of the first nodes (K11, K12, K13), which represents an intended and/or a maximum possible current consumption or output of the first node (K11, K12, K13), is processed by checking whether a current value in the piece of current information (SI) fulfils a predetermined criterion in respect of a possible current value (MW) of the energy feed-in point (ESP). The possible current value (MW) is determined by a differential formed from the predetermined maximum current of the energy feed-in point (ESP) and the actual current. Finally, depending on whether the criterion at the first node (K11, K12, K13) is fulfilled or not, a message is transferred which confirms or denies the current consumption or output to the first node (K11, K12, K13).
