Abstract
Dynamic Security Regions (DSR) are tridimensional graphics that evaluate the power system security when the system is divided into three generation groups, and the generated power is transferred among them. They allow the evaluation of different generation scenarios considering the security limits for the damping ratios associated with electromechanical oscillation modes. The main problem in obtaining the DSR is the high computational effort required due to the several power flows and modal analyses. This paper presents an efficient methodology based on the Particle Swarm Optimization method to obtain DSR. The results obtained for the New England test system are promising in the face of accuracy and the reduced computational burden.
