What Is a Microgrid?

A microgrid''s power supply kicks in instantaneously, and the system runs as long as needed — at least until the power supply from the central utility grid stabilizes and returns to service. When this happens, the switch is closed back in so the generating capacity can synchronize with the grid before it returns to its pre-outage state.
