摘要：
A microgrid is re-synchronized to a main grid or substation by determining a degree of bus angle or frequency mismatch and bus voltage mismatch between the microgrid and the main grid or substation prior to re-synchronization, determining an amount of power adjustment needed to reduce the bus angle or frequency mismatch and bus voltage mismatch to below respective predetermined thresholds, determining at least one participation factor for each microgrid bus, each participation factor indicating an amount of influence power injection by the corresponding bus has on the bus angle or frequency mismatch or on the voltage mismatch, allocating the amount of power adjustment to the microgrid buses in proportion to the participation factors assigned to the buses, and re-synchronizing the microgrid to the main grid or substation responsive to the bus angle or frequency mismatch and bus voltage mismatch satisfying the respective predetermined thresholds.
