Abstract (en)
The method involves providing a multi-objective optimization algorithm (A) for determining a value of a discrete variable (Vi) that is representative of activity of a set of electricity consumption sources (mi) or electrical appliances. An error function (F) entering total measured consumption (S) of the sources is minimized. A cross population of crossed individuals chosen in a pseudo-random manner by taking census probability (qj) into account is generated, and a current population is upgraded by adding individuals selected from the crossed individuals. An independent claim is also included for a device for identification of electricity consumption sources.
Abstract (fr)
La présente invention concerne un procédé et un dispositif d'identification de sources de consommation et/ou de production, à partir de données représentatives d'au moins une consommation globale (s) mesurée dans au moins une installation (2) sur au moins un intervalle de temps (t x ) défini, caractérisé en ce qu'au moins un algorithme (A) d'optimisation multi-objectif, utilise des données comprenant, pour chacune des sources (m i ), au moins une information relative à la consommation nominale (e i ) et au moins une information relative à la probabilité (p i ) de consommation au cours dudit intervalle de temps (t x ), ledit algorithme (A) d'optimisation multi-objectif déterminant la valeur d'une variable discrète (v i ) représentative de l'activité ou de l'inactivité des sources (m i ), à partir, d'une part, de la minimisation d'une fonction (F) de l'erreur entre la consommation globale (s) mesurée et la somme des produits des variables discrètes (v i ) et des puissances nominales (e i ), et, d'autre part, de la maximisation d'une fonction (G) de la probabilité moyenne d'activité des sources (m i ).
