Abstract

For several reasons, particularly due to the mismatch in the feeder impedance, accurate power sharing in islanded microgrids is a challenging task. To get around this problem, a distributed event-triggered power sharing control strategy is proposed in this paper. The suggested technique adaptively regulates the virtual impedances at both fundamental positive/negative sequence and harmonic frequencies and, therefore, accurately share the reactive, unbalanced, and harmonics powers among distributed generation (DG) units. The proposed method requires no information of feeder impedance and involves exchanging information between units at only event-triggered times, which reduces the communication burden without affecting the system performance. The stability and inter-event interval are analyzed in this paper. Finally, experimental results are presented to validate the effectiveness of the proposed scheme.
