This paper investigates a frequency coordination control strategy for islanded microgrid. The dynamic process is divided into three levels including the dynamic support, droop control and zero error regulation. The control strategy is classified into primary and secondary frequency regulation. Simulation is performed on DIgSILENT and the results verify the effectiveness of the proposed control strategy and improve the performance of system frequency regulation.

Traditional decoupling control strategy of doubly-fed induction generator (DFIG) wind turbine makes little contribution to system inertia and do not participate in the system frequency control, the synchronization of large-scale wind power requires wind turbine have the ability to participate in the regulation of power system frequency. This paper adds a frequency control segment to traditional DFIG wind turbine and considers the doubly-fed wind turbine operating on the state of the super-synchronous speed, by analysis the effect of inertia and proportional control strategies, a fuzzy control strategy which combines the advantages of the former two control strategies is proposed, simulation results show that this control strategy can more effectively improve the system frequency response.
