Abstract

L'invention concerne un procédé, un système et une unité de régulation destinés à déterminer l'état opérationnel d'au moins un dispositif consommant de l'énergie électrique (2) et de le commander. Pour chacun des divers états opérationnels du dispositif (2), un modèle de la consommation d'énergie caractéristique associé aux divers états est créé. La consommation d'énergie actuelle du dispositif (2) est continuellement comparée à la consommation d'énergie caractéristique, en fonction du modèle, pour l'état opérationnel souhaité, et le niveau auquel l'état opérationnel courant du dispositif (2) correspond à l'état opérationnel souhaité est déterminé par cette comparaison. Une action prédéterminée est amorcée lorsqu'un écart se crée entre l'état opérationnel courant et l'état opérationnel souhaité.
