Using A Statcom to Enhance Stability of A Grid Connected Wind Power System

This paper presents the simulation results of using a static synchronous compensator (STATCOM) to improve damping of a grid connected wind power system (WPS). The operating performance of the studied WPS is simulated by an equivalent doubly fed induction generator (DFIG) driven by an equivalent wind turbine (WT). PID Damping controller of the proposed STATCOM is designed to reduce the fluctuation of the system under various operating conditions. A time-domain scheme based on a nonlinear system model subject to a three-phase short-circuit fault at the power grid is utilized to examine the effectiveness of the proposed control schemes. It can be concluded from the comparative simulation results that the proposed STATCOM joined with the designed controller is shown to be better for improving the stability of the system subject to a severe disturbanc
