摘要：
Aiming at the problem of poor coordination between PQ control/droop control and micro-sources such as photovoltaic generation, wind power coordination in AC micro-grid, this paper uses DC voltage control strategy of AC micro-grid with to obtain better cooperation and coordination between DC voltage control and photovoltaic generation, wind power in AC micro-grid. But when DC voltage control is used, the constant voltage control strategy of micro-sources cannot be achieved. For improving the constant voltage control strategy, a coordinated control strategy based on the improved constant voltage control and DC voltage control is proposed. The Matlab/Simulink simulation results show that the proposed control method is effective and feasible. © 2020, Editorial Board of Acta Energiae Solaris Sinica. All right reserved.
