Enhancement of voltage stability of autonomous wind power generation system using DSTATCOM

Wind as renewable energy potential is abundantly available at remote locations. This can be harnessed by using the rugged induction generator. However there is a dynamic requirement of reactive power as the load changes. A DSTATCOM has been proposed in this paper to cater for the dynamic requirement of the reactive power for the Induction generator with the change in load and to stabilize the terminal voltage of the wind generator under fault conditions. The paper simulates the autonomous system consisting of wind turbine, induction generator along with a DSTATCOM on a MATLAB platform and studies the stabilization of the voltage under varying load and different fault conditions.
