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.2 A microgrid can operate in either grid-connected or in island mode, including entirely of-grid applications. Figure 1 shows one example of a microgrid.
