摘要

With further research on integrated energy systems and energy interconnection, the small-signal stability of wind power integrated system is becoming increasingly dramatically. This paper adopts a coordinated approach using eigen-analysis and time simulation for studying the impact of PSS as well as determining the PSS location and optimizing parameters through the residue index and probabilistic sensitivity indices (PSIs). Two types of PSS are implemented on a 2-area 4-unit and 8-unit 24-bus power systems with wind power to get comparative analysis on different PSSs improvement of system damping characteristics. The results obtained by case studies show that the PSS second-order model has stronger robustness to improve the system damping, and the selection of PSS types with coordinated optimization can affect the effectiveness of wind power integrated system damping performance improvement.
