When the main electric grid loses power, the microgrid goes into island mode (i.e., operates independently of the main electric grid) and serves its own customers with the generation and other DERs (i.e., batteries or vehicle-to-grid electric vehicles) operating within the microgrid. In terms of microgrid design, this

Types of microgrids, with examples | Cummins Inc.

Microgrids are not fundamentally different from wide-area grids. They support smaller loads, serve fewer consumers, and are deployed over smaller areas. But microgrids and wide-area grids have the same job within the power generation eco-system, distributing electricity, and the same constraints, perfectly matching generation and load at all times.
