Abstract

Renewable sources often produce power and voltage varying with natural conditions. In that wind power generation having much important role in power system especially under integration of high penetration level of wind energy to grid, but grid connection bring problem of voltage sag, swell, voltage fluctuation. Most of the wind generator are use induction generator (IG), therefore it requires more VArs from grid side, so voltage stability problem take place. In this paper according to voltage fluctuation caused by aerodynamic aspects of wind farm, the practical solution provide by using STATCOM. Also STATCOM is used as a dynamic reactive power compensator to stable the voltage at PCC. Wind turbine connected to squirrel cage induction generator is modelled using MATLAB simulation software to analyze the power quality problem where STATCOM is introduced as an active voltage and reactive power supporter to increase the power system stability.
