摘要：
Distributed consensus-based control methods are widely applied to microgrids. However, these control highly depend on the communication between distributed generators. In the control system, existence of communication and control time delays would significantly affect the system performance and the microgrid stability. This paper analyses the influence of communication and control time delays on consensus-based active power distributed control methods of microgrids, and a stability criterion of time delays is proposed. Moreover, a consensus-based control strategy of microgrids considering the influence of system time delays is designed. The proposed control strategy can stand longer time delays compared to traditional control strategies. Correctness and effectiveness of the strategy proposed in this paper are verified with the simulation results under various conditions. © 2019, Power System Technology Press. All right reserved.
