Projet “Grid Power for Sustainability” (GPS) : une première mondiale couplant 3 micro-grids en Ile-de-France pour tester des systèmes énergétiques intelligents

Soutenus par l’Union européenne et la Région Ile-de-France, 5 start-up et des laboratoires dont le Laboratoire de météorologie dynamique (LMD, CNRS/École polytechnique/ENS Paris/Sorbonne Université), joignent leurs forces pour déployer des systèmes avancés de pilotage énergétique au sein de trois campus intelligents. Le projet optimisera en temps réel une multitude d’équipements (compteurs, flux télécoms sécurisés, logiciels de pilotage, station d’autopartage de véhicules, production d’électricité photovoltaïque, éclairage intelligent…) et étudiera les interactions entre plusieurs systèmes micro-grids.
