In order to improve smooth control of output power of megawatt variable pitch controlled wind turbine at high wind speed, an optimized fuzzy PID algorithm is proposed which includes PID and fuzzy control. The initial and the adjusted values of three parameters of this controller are given by Ziegler-Nichols tuning method and fuzzy control method. At the same time, variable weight synthesis of integrated time and absolute error (ITAE) index, overshoot index and settling time index of the system is used for establishing the objective function. Genetic Algorithm (GA) is used for optimizing fuzzy rules of fuzzy PID controller and obtaining the optimized parameters. A simulation validates the proposed method. We take a 1.5MW doubly fed induction wind generator (DFIG) as the subject. With calculation and comparison of the standard deviation of output power before and after rules optimization, it indicates that smoothness of output power becomes better. The control effect has been further improved as well.
