Abstract

Selon la présente invention, une unité d'acquisition d'informations de puissance (110) acquiert périodiquement la quantité d'énergie achetée à des intervalles d'une période d'acquisition. Une unité d'estimation (120) estime, sur la base de la quantité d'énergie acquise, la quantité d'énergie qui sera achetée durant tout un temps unitaire. Une unité de détermination d'état opérationnel (140) détermine, sur la base de la quantité estimée d'énergie et d'une quantité cible prédéterminée, l'état opérationnel d'un dispositif électrique (300). Une unité de commande (150) commande le dispositif électrique afin que le dispositif électrique fonctionne dans l'état opérationnel déterminé à partir du moment où l'état opérationnel est déterminé par l'unité de détermination d'état opérationnel (140) jusqu'à ce qu'une période d'inhibition de changement plus longue que la période d'acquisition s'écoule.
