The power output of wind turbine (WT) is unpredicted and irregular, large scale wind power integrated to power grid influences the power system stability heavily. The multi-functional flexible power conditioner (FPC) is a flywheel energy storage system (FESS) based on doubly-fed induction generator (DFIG), which can perform functions including energy storage, active and reactive power generation. To enhance the power output characteristics of WT, a novel configuration of FPC associated to WT (WT-FPC) is proposed. According to the configuration and control targets of WT-FPC, the control strategies are studied. The active power of the associated system is regulated based on a fuzzy logic inference system, and machine terminal voltage was controlled by regulating the reactive power of FPC. The model of WT-FPC is established and the timedomain simulations are performed using MATLAB/Simulink. The simulation results show the feasibility and effectiveness of the proposed WT-FPC and its control strategies, and the operation characteristics of the WT connected to the grid are enhanced evidently.

Moc wyjściowa turbiny wiatrowej jest nieregularna i trudna do przewidzenia. W celu poprawy charakterystyki mocy turbiny wiatrowej zaproponowano nowy układ FPC (flexible power conditioner). Do sterowania mocą czynną użyto regulatora z logiką rozmytą a napięcie wyjściowe było sterowane przez kontrolę mocy biernej.
