Abstract

L'invention concerne entre autres un procédé mis en œuvre par un dispositif de commande, le procédé comprenant les étapes suivantes : obtenir des informations de programmation indicatives d'une quantité d'énergie électrique qui doit être transmise à au moins un point d'accouplement entre une zone de réseau local et un réseau électrique public pendant une durée prédéfinie, un premier procédé de transmission de l'énergie électrique à l'intérieur de la zone de réseau local s'écartant au moins temporairement d'un deuxième procédé de transmission prédéfini du réseau électrique public, la zone de réseau local étant électriquement isolée du réseau électrique public au point d'accouplement ; et commander et/ou réguler au moins un élément inclus dans la zone de réseau local, la commande et/ou la régulation étant basée au moins en partie sur les informations de programme reçues. L'invention concerne également un dispositif destiné à mettre en œuvre et/ou commander ce procédé, un système comprenant au moins un dispositif destiné à mettre en œuvre et/ou commander ce procédé et un programme informatique destiné à mettre en œuvre et/ou commander ce procédé par le biais d'un processeur.
