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]
