  • Patent number: 11451065
    Abstract: A system and method for synchronizing a utility grid and a microgrid including a diesel generator, a photovoltaic array and a wind turbine. In a grid connected mode, a microgrid voltage, a microgrid frequency and a microgrid phase angle are controlled by a grid side converter which generates a preset reference power at the utility grid frequency; and provides a real power and a reactive power to each of a plurality of loads. In an island mode, the diesel generator operates at a constant speed to generate power at the reference frequency and communicates the reference frequency to a wind turbine, and the microgrid supplies the real power and reactive power to each of the plurality of loads. In a resynchronization mode, a switched capacitor bank is charged to provide the voltage needed to reconnect the microgrid to the utility grid.
