Decentralized Robust Power System Stabilizer Design

This paper suggests a method for designing PSS to damp multi-machine power system oscillations.  The method is based on robust control theory. First, the conventional method for designing robust controller in LMI framework is illustrated. Then, the suggested method is given, in which, a PID output feedback controller is tuned using the LMI approach. Mostly, the classical methods are used t...

Robust Fuzzy Stabilizer Design for Power System

In this paper, a robust method to changes of work points for stability of the power systems equipped with PSS controllers has been presented. In the proposed method, at first the coefficients of PSS controller for different work points of the system have been optimized off line by PSO algorithm and then a fuzzy controller to select the best power system stabilizers have been optimized according...

Design of Genetic-Algorithm Based Robust Power System Stabilizer

This paper presents a systematic approach for the design of power system stabilizer using genetic algorithm and investigates the robustness of the GA based PSS. The proposed approach employs GA search for optimal setting of PSS parameters. The performance of the proposed GPSS under small and large disturbances, loading conditions and system parameters is tested. The eigenvalue analysis and nonl...

A Robust TFPDC Based Power System Stabilizer

This paper presents a robust Takagi-Sugeno Fuzzy Parallel Distribution Compensation (TSFPDC) based Power System Stabilizer (PSS) for damping power system low frequency oscillations. The main motivation of using this controller is minimizing the efforts of load disturbances and achieves the desired level of robust performance in the presence of modeling uncertainties. The effectiveness of the pr...
