A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to operate in grid-connected or island mode. Microgrids can operate in several different modes depending on the power demand, the availability of energy sources, and the connection. . The key distinguishing feature of a microgrid is its ability to: 3. Key Components of a Microgrid 3.
