Abstract The power output of wind generator (WG) is unpredicted and irregular, and large scale wind power integrated to grid influences the power system stability heavily. The multi-functional flexible power conditioner (FPC) is a flywheel energy storage system based on doubly fed induction generator (DFIG), which can perform functions including energy storage, active and reactive power generation. To enhance the characteristics of WG power output, a novel structure of FPC associated to WG (WG-FPC) is proposed. According to the structure and control targets of WG-FPC, the control strategies are studied, regulating the active power of the system used fuzzy logic inference and machine terminal voltage is controlled by regulating FPC reactive power. The model of WG-FPC is built up and simulation is done using Matlab/Simulink. The simulation results show the feasibility and efficiency of the proposed WG-FPC and control strategies, and the operation characteristics of the WG connected to the grid are enhanced evidently.

Key words： Wind generate flexible power conditioner fuzzy logic inference power regulation voltage control
