This paper discusses the dynamic behavior of the stand-alone parallel operation system using two wind turbine-generators by our dynamic simulation model. The stand-alone parallel operation system is composed of two Darrieus-Savonius hybrid turbines, two load induction generators, one inverter, batteries, and one controller. This system is mainly operated at the maximum power coefficient points of two parallel turbines by the inverter frequency control for a simple system composition and high power extraction. The computed results of the dynamic behavior of the system to various wind speed changes shows that our control scheme of the parallel operation system is effective.

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.
