Island resort smart microgrid

The micro grid relies on four diesel generators (2.6 megawatts in total) to start energy production. Once the grid reaches 240V/50Hz, the Energy Storage System (ESS) and loads are connected to the grid and ARTICS Smart Energy takes over to manage the overall system. The diesel generators will be used for emergency mode in case of sudden outage.
