Abstract

Wind energy is one of the extra ordinary sources of renewable energy due to its clean character and free availability. We used a static synchronous compensator (STATCOM) to supply the reactive power and voltage support to a wind farm equipped with Induction Generators(IGs) and power system during grid faults. Also, the STATCOM is used in steady state to supply reactive power in power system.  Simulation results show that the wind turbine bus voltage is quickly reestablished shortly after the fault has been cleared, and therefore, the wind turbine remains in service during the presence of STATCOM. The results prove the effectiveness of the proposed STATCOM controller in terms of fast damping the power system oscillations and restoring the power system stability. The choice of this study is justified by simulation in MATLAB.
