Abstract

Sub Synchronous Resonance (SSR) poses a serious threat to the stability of modern power systems, particularly those integrating Doubly Fed Induction Generator (DFIG) based wind farms with series-compensated transmission lines. The increasing penetration and stochastic nature of wind power further intensify SSR-related oscillatory instability, necessitating effective damping solutions. This paper proposes an optimized Static Synchronous Series Compensator (SSSC) based control strategy for mitigating SSR in wind integrated power systems. Detailed dynamic models of wind turbines and DFIGs are developed, while wind power uncertainties are incorporated using a probabilistic point estimation method. The SSSC is employed as the primary damping device, and its control parameters are optimally tuned using the Non-Dominated Sorting Genetic Algorithm (NSGA). Simulation results on a benchmark test system demonstrate that, in the absence of compensation, severe sub-synchronous oscillations drive the system toward instability. In contrast, the proposed SSSC scheme significantly suppresses oscillation amplitude, ensures rapid damping, and restores system stability. Comparative analysis confirms superior performance over conventional compensators, including TCSC, in terms of damping speed, robustness, and overall stability enhancement
