Power Quality Management Using FACTS Device for Grid-Connected PV Solar and Wind Turbine Systems

Abstract
This study investigates the use of Flexible AC Transmission System (FACTS) devices for power quality management in grid-connected photovoltaic (PV) solar and wind turbine systems within the GA West Municipal District electricity grid in Accra. With a growing reliance on renewable energy sources for sustainable solutions, understanding their impact on low-voltage (LV) networks and effective management strategies is crucial. The study aims to assess the effects of hybrid PV and wind systems, modeling and simulating the GA West Network and IEEE-Low-Voltage Distribution Network (LVDN) and focusing on power factor, active, and reactive power. A 19-busbar test network was modeled to evaluate PV and wind turbine integration with the grid, and IEEE-LVDN was used for validation. The study employed the MATLAB/Simulink simulations. Results show that FACTS devices substantially improve power factor, achieve near-unity levels, and enhance overall network performance by reducing active and reactive power losses. The analysis confirms that FACTS devices boost system capacity, stability, and dynamic behavior. The findings indicate that integrating FACTS devices in grid-connected renewable systems effectively manages power quality and optimizes network performance.
