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.

Architectures are needed to manage the flow of energy from different types of sources into the electrical grid. Thus, the microgrid can be classified into three topologies: Power sources with AC output are interfa. Microgrids provide less than 0.3 percent of U.S. electricity, but their capacity has grown by almost 11 percent in the past four years. [pdf]
