Abstract:
To enhance the stability of the power system and the system damping is improved, supplementary damping controller is required connected with a power system in the form of PSS and POD. In order to achieve better performance and optimal response of the controller, proposed a technique a new optimization is known Dolphin Echolocation Optimization (DEO) algorithm. Echo is sonar similar used by the dolphin for navigation and hunting. This ability in dolphin made her development of a new optimization method. Therefore, the process for tuning optimal individual and coordinated design of (PSS and UPFC-POD) using (DEO) algorithm gave the best damping resulting compare with (PSO) algorithm.
