This study investigates how a combination of Multi-Band Power System Stabilizers (MBPSS) and Flexible AC Transmission System (FACTS) devices might improve stability in power networks with significant wind energy penetration under fault conditions. Maintaining system stability becomes increasingly important as wind power integration rises, especially when there are disruptions that could cause electromechanical oscillations. The study uses MBPSS to model a wind turbine powered by a Doubly-Fed Induction Generator (DFIG) and assesses the performance of several FACTS devices, including Unified Power Flow Controllers (UPFC), Static Synchronous Series Compensators (SSSC), and Static Synchronous Compensators (STATCOM). According to simulation results, combining these technologies reduces oscillations significantly—for example, damping times decreased from 8 s (without controllers) to 3 s (with MBPSS and UPFC), and frequency deviations were maintained within ±0.5 Hz. These results demonstrate that the UPFC and MBPSS combination is the most effective in stabilizing the grid when wind energy levels are high.
