PID controller based pitch angle controller for the frequency regulation and active power control in a wind turbine and diesel engine powered hybrid power system, is presented in this paper. For testing the prosed controller, variable wind speed pattern is used for realization of real time wind behavior. Furthermore, the variable load is also connected to the hybrid power system to test the efficacy of the prosed controller. The system is modelled and simulated in MATLAB environment and results obtained are compared with and without pitch angle controller. The frequency deviations in PID based pitch angle controller is less than the without controller.
