Microgrid
Microgrid. A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and in island mode. [2] [3] A '' stand-alone microgrid '' or '' isolated microgrid '' only operates off-the-grid and cannot be connected to a wider electric power system. [4]

Microgrids are similar, but also have the capability to connect synchronously to a large network. Island grids are typically the result of geographical circumstances that render the connection to a large network costly or even impossible. Microgrids, in contrast, are designed to increase the security of supply in case the large network breaks down.
