A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. It is able to operate in grid-connected and in island mode. A ''stand-alone microgrid'' or ''isolated microgrid'' only operates off-the-grid and cannot be connected to a wider electric power system. Very small microgrids are called nanogrids. A grid-connected microgrid normally operates connected to and synchronous with the traditional
