Voltage Flicker Mitigation of Wind Farm Using a STATCOM

Abstract

this paper investigates the use of static synchronous compensator (STATCOM) to mitigate the voltage
flickers or voltage fluctuations of wind farm equipped with wind turbine driving squirrel cage induction generators.
60MW wind turbine generator system is connected to grid through step up transformer and transmission line.
Conventional PI control scheme is adopted for controlling of STATCOM. The MATLAB based simulation result shows
that STATCOM significantly reduces the voltage flickers caused by wind speed variation and enhance the power quality
of the system.
