Abstract
The integration of renewable energy sources, such as solar and wind, into modern power grids presents challenges in maintaining power quality and stability, particularly under fault conditions like voltage sags and swells. This research focuses on the design and optimization of Dynamic Voltage Restorers (DVRs) to enhance power quality and Fault Ride through (FRT) capabilities in hybrid solar-wind systems. Using advanced control strategies, including fuzzy logic and adaptive Bee Colony Optimization (ABCO), DVRs mitigate voltage disturbances and optimize the parameters of Proportional-Integral (PI) controllers. The study examines system performance across three scenarios: without DVR, with DVR using fuzzy logic control, and with DVR employing ABCO. Results demonstrate progressive improvements in voltage stability, power quality, and total harmonic distortion (THD) reduction, establishing DVRs as critical components for integrating renewable energy sources into reliable and resilient grid systems
