Abstract The rapid penetration of renewable energy sources (RES) into modern power systems has introduced new challenges in maintaining grid stability, particularly during fault conditions. Hybrid renewable systems that combine wind and solar energy provide clean and sustainable generation, but their intermittent nature and sensitivity to disturbances often compromise reliability. Additionally, the integration of electric vehicle (EV) charging infrastructure, while essential for sustainable transport, imposes further dynamic stress on the grid. This paper proposes a STATCOM-assisted control strategy to enhance the Fault Ride-Through (FRT) capability of a grid-integrated hybrid RES with EV charging stations. The hybrid system model, consisting of a wind energy conversion system, photovoltaic array, and a fast-charging EV station, is interfaced through back-to-back converters and a DC-link. Under fault conditions such as voltage sags and swells, the STATCOM provides dynamic reactive power support, stabilizes the DC-link voltage, and mitigates voltage distortions at the Point of Common Coupling (PCC). Simulation studies conducted in MATLAB/Simulink demonstrate that the proposed approach effectively improves voltage stability, reduces harmonic distortion, and ensures compliance with IEEE-519 harmonic limits and FRT grid codes. Results show that the STATCOM enhances power quality and allows continuous EV charging, even during grid disturbances. The proposed method thus strengthens the reliability of hybrid RES integration, making it more suitable for large-scale deployment in future smart grids.
