Abstract

See full text

Systems and methods are disclosed for distributed cooperative control strategy between a microgrid and a main grid by providing distributed synchronization and reconnection of the distributed generators with sparse communication channels, wherein each distributed generator only receives information from neighboring generators; receiving a voltage phase angle difference and a voltage magnitude difference by a proportional integration (PI) controller to adjust the output of the distributed generator at a leader node, wherein each distributed generator shares an output frequency and a voltage with neighbors; achieving a consensus behavior between all the distributed generators; sharing power generation among the distributed generators; and synchronizing the microgrid with the main grid for a seamless reconnection after islanding.
