Medium Voltage Microgrid Islanding

SOCOMEC has taken part in the French demo project Nice Smart Valley as the energy storage sys tem manufacturer, as part of the European project INTERFLEX. The aim is to demonstrate the feasibility and perfo rmance of a medium voltage microgrid, based on several distribu ted storage systems. This paper describes the tested use cases such as: Islanding with or without black start, synchro-coupling, voltage/frequency generation in the limits required by the standards, grid stability data monitoring and wireless management of several storage equipment for longer backup. All functionalities have been analyzed by theoretic al study, experimental tests in a laboratory and in real cond itions on the island.
