Abstract:
The increasing global demand for sustainable and clean energy has accelerated the integration of renewable energy sources such as solar photovoltaic (PV) and wind energy into conventional power systems. However, the combination of these variable energy sources introduces power quality issues, particularly harmonic distortion, due to nonlinear switching devices and fluctuating generation patterns. Harmonics adversely affect system stability, efficiency, and the lifespan of electrical components, making their mitigation a crucial aspect of hybrid renewable system design. This review paper provides a comprehensive analysis of harmonic generation mechanisms in integrated solar-wind energy systems and evaluates the role of Flexible AC Transmission System (FACTS) controllers in minimizing these distortions. Various FACTS devices such as Static VAR Compensators (SVC), Static Synchronous Compensators (STATCOM), and Unified Power Flow Controllers (UPFC) are discussed in terms of their operational principles, control strategies, and harmonic suppression capabilities. The paper also compares conventional control methods with advanced techniques like fuzzy logic, artificial neural networks, and adaptive controllers used in FACTS-based harmonic mitigation. Furthermore, the study explores grid codes, IEEE standards for power quality, and recent trends in hybrid renewable grid interfacing. The review concludes that the coordinated operation of FACTS controllers significantly enhances power quality, voltage stability, and harmonic reduction efficiency in integrated renewable systems. Future research directions focus on the development of intelligent hybrid control strategies and cost-effective FACTS configurations optimized for large-scale renewable integration.
