Power system stabilization is a major issue in the area of power systems research. The Conventional Power System Stabilizer (CPSS) parameters are tuned by using Genetic Algorithm to achieve proper damping over a wide range of operating conditions. The CPSS lack of robustness over wide range of operating conditions. In this paper type-2 Fuzzy Logic Power System Stabilizer (FLPSS) is presented to...
