摘要

To solve the problem of reactive power and unbalanced power sharing in islanded AC microgrids with limited communication, this paper proposed a distributed secondary control strategy based on the quantization transmission method and event-triggered communication. In this strategy, each distributed generator communicates with neighbors only when the triggering condition is satisfied. At the same time, the transmission data is compressed by the quantizer to reduce the amount of transmission data. Then, the analysis of the designed control indicates the realization of the reactive power and unbalanced power sharing and the reduction of the communication burden. The stability of the designed control method is proved by LaSalle’s invariant-set principle. Finally, the simulation results are given to verify the proposed method.
