Abstract

The improvement of a grid-connected wind microgrid’s Low Voltage Ride-Through (LVRT) capability using a Static Synchronous Compensator (STATCOM) is investigated in this research. The increasing penetration of wind energy into modern power systems necessitates advanced control strategies to maintain grid stability during voltage disturbances and fault conditions. In this study, a STATCOM is employed with an effectively tuned PI controller to provide enhanced dynamic response, voltage regulation, and reactive power support during grid disturbances. The improved STATCOM controller demonstrates superior performance under both symmetrical and asymmetrical fault conditions compared to conventional tuning techniques. A 16 MW wind microgrid based on Doubly Fed Induction Generators (DFIGs) is modeled and simulated in MATLAB/Simulink to evaluate system behavior under various grid fault scenarios. The performance of the STATCOM is analyzed in terms of voltage recovery, reduction of peak voltage sag, reactive power compensation, damping of post-fault oscillations, and overall system stability during LVRT events. Simulation results indicate that a properly tuned STATCOM significantly enhances the voltage profile at the Point of Common Coupling (PCC), improves fault ride-through capability, ensures compliance with grid code requirements, and contributes to the reliable and stable operation of grid-connected wind-based microgrids under severe fault conditions effectively and sustainably.
