Abstract

L'invention concerne un procédé et un système pour intégrer un appareil (2a) électrique dans un réseau (1) d'alimentation en énergie. Selon l'invention, l'appareil (2a) électrique peut être relié avec une commande (3) de réseau pour commander au moins un paramètre de réseau et l'appareil (2a) électrique présente une identification explicite qu'il communique à la commande (3) de réseau après avoir préalablement demandé une connexion. L'utilisation d'une unité (4) de gestion supplémentaire avec un accès aux états du réseau (1) d'alimentation en énergie permet de déterminer une configuration d'appareil optimale au moyen de systèmes (10) basés sur la régulation et de la transmettre par l'unité (4) de gestion à l'appareil (2a) électrique qui demande une connexion. La mise en oevre de la configuration d'appareil dans l'appareil (2a) électrique donne lieu à une deuxième demande de connexion suivie d'une authentification dans le réseau (1) d'alimentation en énergie. Cela permet de garantir que les appareils (2a, 2b, 2c) électriques des composants (9a, 9b, 9c) de réseau associés ne soient pas configurés sur site et que leur commande est garantie dans des cellules de faible étendue se gérant elles-mêmes sous la forme de grappes d'appareils (2b, 2c) électriques interconnectés.
