Abstract

L'invention porte d'une façon générale sur le domaine de l'alimentation en énergie. Plus précisément, la présente invention concerne un procédé pour stabiliser un système d'alimentation en énergie électrique comprenant au moins trois plans d'alimentation. Dans un plan d'alimentation extrême inférieur, ce qu'on appelle le plan de basse tension, des abonnés au réseau, en particulier des consommateurs sont connectés ; à chaque abonné correspond un dispositif de mesure intelligent, ce qu'on appelle un compteur intelligent. Au moyen des dispositifs de mesure intelligents, par observation de caractéristiques telles que, par exemple, une fréquence du réseau, une tension du réseau, etc., une situation du réseau caractérisée par des paramètres prédéterminés est surveillée dans au moins un segment de réseau partiel du système d'alimentation en énergie (2). Les dispositifs de mesure intelligents enregistrent les modifications décentrées des caractéristiques ainsi que de la situation du réseau (3) puis, en fonction d'une priorité prédéterminée de l'abonné considéré, une consommation de puissance ou d'énergie de l'abonné considéré est commandée par le dispositif de mesure intelligent concerné en fonction de la situation constatée du réseau (4). Ceci signifie que l'abonné du réseau est déconnecté au moyen du dispositif de mesure intelligent correspondant, ou que sa consommation de puissance ou d'énergie est réduite en fonction des priorités (4). Grâce à cette possibilité d'opérer de façon préalable et calculée une déconnexion et/ou une réduction de la consommation de puissance par les abonnés au réseau, il est possible d'éviter d'une façon très simple des instabilités du réseau, puis ce qu'on appelle un blackout.
