A Multiobjective Coordinated Design PSS and FACTS using the Combination of CWT and Prony Methods

This article is introduced a new combination method of CWT and Prony algorithm to scrutiny power system low frequency electromechanical oscillations. Estimation of inter-area and local modes for large scale power systems control is important and the elementary purpose of controller is the damping of these modes. The PSS and FACTS parameters design has become a multi-objective problem. It is solved by NSGA II algorithm. Residual method is exerted to increase damping and the power system controller parameters meet their constraints and practical limits. This method is simulated on 2-area, 4-Generator system. The simulation results showed the suggested method validity to the system stability.
