Abstract

L'invention concerne un système de commande d'énergie équipé d'une batterie de stockage (120), d'un moyen de mesure d'énergie (140), d'un moyen de calcul (150) et d'un moyen de commande de batterie (160). La batterie de stockage (120) est connectée à une ligne électrique (130), qui est connectée à un réseau électrique (20) par l'intermédiaire d'un équipement de réception d'énergie (110). Le moyen de mesure d'énergie (140) mesure l'énergie fournie à la ligne électrique (130) à partir du réseau électrique (20). Pour chaque période de temps de référence dans une période de temps concernée allant d'un instant prédéterminé jusqu'à l'écoulement d'une quantité de temps prédéterminée, le moyen de calcul (150) calcule une valeur prédite pour l'énergie moyenne dans la période de temps concernée ou une valeur prédite pour la quantité d'énergie consommée dans la période de temps concernée, sur la base d'un résultat de mesure provenant du moyen de mesure d'énergie (140). Le moyen de commande de batterie (160) commande la charge/décharge de la batterie de stockage (120) sur la base de la valeur prédite et d'une valeur de référence prédéterminée.
