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

What Is a Microgrid?

A microgrid is a local, self-sufficient energy system that can connect with the main utility grid or operate independently. It works within a specified geographical area and can be powered by either renewable or carbon-based energy resources, such as solar panels, wind turbines, natural gas and nuclear fission. This way, microgrids can continue to operate even
