Recently, voltage-source or current-source inverter-based various FACTS devices have been used for flexible power flow control, secure loading, and damping of power system oscillations. Due to the increasing penetration of Renewable Energy Sources (RESs) such as wind power, maintaining the stability and reliability of the power grid has become a significant challenge. The integration of induction generator-based wind turbines affects grid stability due to their inherent reactive power demand. A static synchronous compensator (STATCOM) is widely recognized as an effective solution for reactive power compensation. This study presents a comparative analysis of grid stability before and after the connection of STATCOM in a grid-connected wind energy system. The study focuses on evaluating key stability aspects such as reactive power support without implementing any control strategies for STATCOM operation. These findings highlight the potential of STATCOM as a robust solution for stabilizing wind power generation in grid-connected applications. The proposed scheme for the grid connected wind energy conversion system is simulated using MATLAB/SIMULINK.
