Application of PI and Super Twisting Drivers to Voltage Regulation of Wind farm via StatCom

In this paper, the steady-state and dynamic behavior of a wind farm with reactive power compensation using a StatCom devices is analyzed. An algorithm and a method for calculating the steady-state of the wind farm with SCIG and the random wind speed is proposed. 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.
