Abstract

Abstract: Distributed generations (DGs) can be used for the power quality enhancement of microgrids. However， load imbalance power cannot be shared accurately among the DGs by using the conventional droop control method for considering the mismatched line impedance. To solve this problem， a novel distributed negative-sequence power sharing method was proposed based on both consensus and adaptive virtual impedance. The negative sequence virtual impedance of each DG was used by this method to achieve accurate negative-sequence power sharing. A multi-agent consistency algorithm was designed to adjust adaptively the negative-sequence virtual impedance， to eliminate the imbalance power sharing error among the DGs， and to implement accurately asymmetric power sharing. The simulation results verified the correctness and validity of the proposed method.

Key words: distributed generation (DG), microgrids, consensus control, negative-sequence virtual impedance, imbalanced power sharing
