It operates in both grid-connected and island modes. A solar photovoltaic microgrid (PV MG) is defined as a group of interconnected loads and SPVSs which acts as a single controllable entity and operates in both grid-connected and islanded conditions. Generally, a conventional SPVS is unable to operate in the islanded mode on its own.
