Abstract

The rising demand for sustainable and efficient energy sources has accelerated the adoption of hybrid renewable energy systems (HRES), particularly those combining solar photovoltaic (PV) and wind power. These systems enhance reliability and energy security but also introduce significant power quality (PQ) challenges most notably, Total Harmonic Distortion (THD). This review explores the key sources of PQ issues in solar-wind hybrids, emphasizing THD origins and impacts. It details system configurations, control strategies, and the role of power electronic converters such as inverters, rectifiers, and MPPT controllers. Various THD mitigation methods are analyzed, including passive/active filters, advanced control techniques (PWM, SVM), and AI-based optimization (fuzzy logic, neural networks, genetic algorithms). Standards from IEEE/IEC are referenced for performance benchmarks. Emerging solutions like UPQC, DVR, smart inverters, and IoT-based monitoring are also discussed, offering a comprehensive outlook on enhancing PQ in modern grid-connected hybrid systems.
