Abstract
This study proposes a novel optimization strategy for tuning the parameters of a Rotor Side Converter (RSC), employing a hybrid approach that integrates three advanced optimization algorithms: Particle Swarm Optimization (PSO), Cuckoo Search Algorithm (CSA), and Grey Wolf Optimizer (GWO). The proposed method is integrated with existing damping techniques on both the grid side, using a Thyristor Controlled Series Capacitor (TCSC) and the wind farm side, utilizing a Supplementary Damping Controller (SDC) to enhance the Sub-Synchronous Oscillation (SSO) damping effectiveness. Based on the IEEE First Benchmark and the IEEE 14-bus system, time-domain simulations and small-signal stability analysis demonstrate that the proposed solution significantly improves the damping performance under critical operating conditions, particularly high series compensation levels and low wind speeds. The MATLAB/Simulink tool was also employed in this study.
