Abstract
A method for synchronization of first and second microgrids, having respective first and second voltages and frequencies. The method includes determining a possible voltage and frequency range, determining an overlapping voltage range, determining an overlapping frequency range, selecting a third voltage within the overlapping voltage range. The method also includes selecting a third frequency within the overlapping frequency range. The method also includes controlling the first microgrid to change from the first voltage and frequency to the third voltage and frequency. The method also includes controlling the second microgrid to change from the second voltage and frequency to the third voltage and frequency. The method also includes connecting the first and second microgrids to each other by closing a switch there between.
