Electrical grid
Microgrid

A microgrid is a local grid that is usually part of the regional wide-area synchronous grid but which can disconnect and operate autonomously. It might do this in times when the main grid is affected by outages. This is known as islanding, and it might run indefinitely on its own resources.

Compared to larger grids, microgrids typically use a lower voltage distribution network and distributed generators. Microgrids may not only be more resilient, but may be cheaper to implement in isolated areas.

A design goal is that a local area produces all of the energy it uses.
