Abstract

Dynamic Security Regions (DSR) are tridimensional graphics that evaluate power system security. For this purpose, the system is divided into three-generation groups. They allow the evaluation of different generation scenarios considering the security limits for the damping ratios associated with electromechanical oscillation modes. The literature shows that Power System Stabilizers (PSS) optimal tuning increases the damping ratios in closed-loop operation, and this paper investigates the PSS tuning on the DSR shape. The DSR is built using a Particle Swarm Optimization based approach, and the results are obtained for the New England test system.
