A microgrid is a group of interconnected loads and distributed energy resources 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. Our researchers evaluate in-house-developed controls and partner-developed microgrid components using software modeling and hardware-in-the-loop evaluation platforms. In contrast to conventional power systems, microgrids exhibit greater sensitivity to fluctuations in demand due to their reduced rotating inertia and predominant reliance on. . A microgrid can be considered a localised and self-sufficient version of the smart grid, designed to supply power to a defined geographical or electrical area such as an industrial plant, campus, hospital, data centre, or remote community.
