Control Strategies and Simulation of Hybrid Microgrid with Multiple Micro Sources

Aiming at the diversity and dispersibility of distributed generations and their loads in microgrid,on based of analyzing the P/Q control strategy and the V/f control strategy with droop control strategy, this paper proposed the P/Q-V/f control strategy. This strategy can realize power sharing to maintain the stability of microgrid voltage and frequency. With the PSCAD/EMTDC similation plotform,the simulation results of switching operating modes and cutting or increasing load in islanding mode can prove the effectiveness and correctness of the proposed control strategy.
