A Robust Reactive Power Sharing Solution For Meshed Multi-PCC Microgrids

In light of the great transition toward renewable energy generation, islanded microgrids are offering a wide opportunity to reach this aim. Hence, power sharing strategies of parallel distributed generation sources are becoming an interesting research point. Traditional droop control is the fundamental decentralized method to reach proper sharing of active and reactive power. Yet, in case of unequal values of the interconnecting line impedances, reactive power sharing errors become remarkable. To resolve this issue, a decentralized power sharing method is suggested in this paper. The chosen microgrid is a multi-Point of Common Coupling (PCC), unlike the majority of research works, which consider mono PCC microgrids. In this paper, synchronization, load variation, communication delay and communication interruption are considered and proved by simulation using MATLAB/Simulink.
