Effective utilization of renewable energies such as wind energy is expected instead of the fossil fuel. Wind energy is not constant and windmill output is proportional to the cube of wind speed, which cause the generated power of wind turbine generators (WTGs) to fluctuate. In order to reduce output power fluctuation of wind farm, this paper presents a output power leveling control strategy of wind farm based on both average wind farm output power and standard deviation of wind farm output power, cooperative control strategy for WTGs, and pitch angle control using a generalized predictive controller (GPC) in all operating regions for WTG. The simulation results with using actual detailed model for wind farm systems show effectiveness of the proposed method.
