摘要
Abstract
In the AC/DC hybrid microgrid,parallel bidirectional power converters(BPCs)can realize large-capacity power transmission to meet the new power system's spatial supply and demand matching.Coordinating and controlling BPCs to realize power proportion sharing while occupying fewer resources is the research difficulty of BPCs control in AC/DC hybrid microgrids.Therefore,this paper designs an event triggering improved consistency coordination control strategy for BPCs.Based on the normalized droop control,an improved proportional power consensus algorithm is proposed to realize high-precision proportional power sharing among BPCs.On this basis,an event trigger improved consensus algorithm is established based on the BPCs proportional power error,and a pre-judgment threshold of the trigger function is preset,thereby reducing the number of system communications in a stable state.The simulation results show that the traffic volume of the proposed method is reduced by more than 98％compared with the basic consensus algorithm;Meanwhile,the proposed method has better control performance compared with the existing literature.关键词
