Scattering Transformation Based Wide-Area Damping Controller of SSSC Considering Communication Latency

This paper presents a new design of scattering transformation-based wide-area damping controller for static synchronous series compensator (SSSC) to enhance power system stability in the presence communication latency. The proposed control approach is comprised classical structure addition two transformation ports. These ports are inserted between and (WADC) regulate signal exchange. Since WADC centralized controller, time delay imperfections considered stage. formulated as an optimization problem where parameters optimized using particle swarm (PSO) algorithm. improves performance due achieved compensation. controller's effectiveness demonstrated by implementing several case studies under different disturbance scenarios. benchmarked with based on lead-lag structure. results confirm robustness against uncertainty. efficacy confirmed reduce delay, resulting better stability.
