Distributed Secondary Control for Islanded Microgrids with Event-triggered Strategy

This paper investigates the consensus problem of the frequency and voltage in islanded microgrid. A distributed secondary control strategy is proposed which is based on the multi-agent cooperative control method combined with event-triggered mechanism and achieves the frequency and voltage restoration. During the control process, the controller is designed to work as necessary to mitigate the communication burden and the number of executions. In addition, the influence of communication delay on control algorithm is taken into account in this paper. Finally, several simulation results verify the effectiveness of the proposed methods.
