The increasing penetration of renewable energy sources has intensified power quality and stability challenges in grid-connected hybrid renewable energy systems. Although several studies have investigated the integration of solar photovoltaic (PV) and wind energy with the utility grid, limited attention has been given to the comprehensive enhancement of power quality using a Unified Power Quality Conditioner (UPQC) under dynamic operating conditions. This paper proposes a novel grid-connected hybrid renewable energy system comprising solar PV, wind energy conversion, and a UPQC-based FACTS device to simultaneously mitigate voltage disturbances, compensate reactive power, suppress harmonic distortion, and improve overall grid stability. A detailed MATLAB/Simulink model is developed to evaluate system performance under varying solar irradiance, wind speed, and load disturbances. The effectiveness of the proposed approach is assessed using voltage profile, power factor, reactive power compensation, total harmonic distortion (THD), and dynamic response as key performance indicators. Compared with conventional grid-connected renewable systems, the proposed configuration provides faster disturbance compensation, superior harmonic suppression, and enhanced system reliability under fluctuating renewable generation. These findings demonstrate that the proposed UPQC-based hybrid renewable energy system offers an effective and practical solution for improving power quality, increasing renewable energy penetration, and supporting the development of reliable, efficient, and sustainable smart grid infrastructures.
