Pitch Angle Control Based Improved Cooperative Co-Evolution in Power Generation System

Abstract:

In this paper, a new controller of the pitch angle of the wind turbine is designed based on improved cooperative co-evolutionary algorithm(ICCEA). The ICCEA is based on general co-evolution model, and can choose evolutionary algorithm for its subpopulations independently, and regulate the probabilities of individuals production to promote the speed of evolutionary according to the characteristic of control system by introducing distribution function. The simulation results demonstrate that the proposed controller can efficiently and steady control the output power of the wind power generation system. Compared with the traditional PID controller, the controller has better control performance.
