Abstract


Maintaining high power quality is essential in modern electrical systems, as even minor distortions significantly impact equipment performance, operational efficiency and system reliability. Power Quality (PQ) issues such as harmonic distortion, voltage instability and frequency deviations pose major challenges to smooth operation of electrical networks. The integration of Renewable Energy Sources (RESs), particularly Photovoltaic (PV) systems, further complicates PQ management due to their intermittent nature. To address these challenges, this research proposes a Unified Active Power Filter (UAPF) that combines both series and shunt compensation techniques for comprehensive PQ enhancement. A PV based High-Gain Integrated Boost-Luo Converter is incorporated to power the DC link while an Improved Artificial Rabbit Optimized Proportional-Integral (IARO-PI) controller ensures precise voltage regulation and stable DC-link voltage. Additionally, a Cascaded Fuzzy Controller governs UAPF operation, enabling adaptive responses under nonlinear and dynamic system conditions. The proposed PV-UAPF system is validated through MATLAB simulations, achieving a substantial reduction in Total Harmonic Distortion (THD) to 0.98% and maintaining near-unity power factor. These results confirm that the integration of renewable energy with intelligent PQ management provides a robust solution for delivering stable, efficient and sustainable power distribution.
