Overview of Microgrid

A major concern in islanded microgrids is frequency regulation. Microgrids are also vulnerable to large disruptions when generators go out due to their low number of generation units. Accordingly, for such disturbances, the system frequency may experience large excursions at a fast rate, potentially compromising system frequency stability [ 59, 60 ].
