Voltage regulation by statcom on wind farm with SCIG using PI and Super-Twisting controllers

In this article the dynamic behavior of a wind farm with reactive compensation is analyzed using a FACTS device (StatCom). The wind generator system includes the models of the wind, turbine and squirrel-cage induction generator speed gear system. A StatCom is used to minimize the effects of the wind speed variation. Two controllers are analyzed in the StatCom; one PI lineal type and the other is a non-lineal robust type known as Super-Twisting, to regulate the voltage magnitude in the connection node.
