Minimization of output fluctuations of wind farm integrated hybrid power system using new pitch controller

In this paper a central supervisory control system based on wind speed data is proposed for calculating reference power for the blade pitch angle of each wind turbine. Low Pass Filter (LPF) technique is used to generate proposed blade control system of wind farm. The wind farm consists of 5 induction generators (IG) and is connected to a multi machine power system composed of 4 synchronous generators (SG) and a load. An extra LPF is used for calculating reference power for IG4 and IG5. Simulations have been done by PSCAD/EMTDC program by using real wind speed data. Simulation results clearly indicate that proposed blade control system can maintain frequency with less energy losses.
