Dynamic Stability Enhancement using PSS and UPFC

Abstract: This research proposes a new PSO-based PSS for the UPFC to dampen power system low frequency oscillations. A power system stabilizer is developed for UPFC to efficiently damp the oscillations of the power system. The parameters of PSS are tuned using the PSO algorithm. The effectiveness of the proposed control technique is tested under various fault scenarios and compared to the GA-based PSS to demonstrate its robust performance using time simulation studies and certain performance indices.
