The inclusion of renewable energy sources such as wind power in power system is steadily increasing around the world. Due to the nature of wind, the output power gets fluctuated according to the wind speed variations. Technologies have been developed to match the generated frequency with grid frequency. In this paper, a supercapacitor have been developed to regulate the output power of wind farms to improve power system reliability and power quality. It considers the integration of the short

This storage device can also be used to reinforce the DC bus during transient, thereby enhancing its low voltage ride through capability. This paper also proposes an operation scheme of wind farm to alleviate power fluctuation by choosing an appropriate control mode and coordinating multiple wind turbines in consideration of grid conditions. This paper deals with three main aspects of WPG are 1) Voltage control, 2) Frequency control and 3) Mitigation of output power variation. Simulation studies are carried out in MATLAB to verify the effectiveness of this proposed system.
