Design of Robust Power System Stabilizer in an Interconnected Power System with Wind Power Penetrations

Abstract

Computer data. Robust PSS design based on inverse additive perturbation in a power system with wind farms has been proposed in this work. The parameters optimization of PSS is formulated based on an enhancement of system robust stability margin. Solving the problem by GA, PSS parameters are automatically obtained. The designed PSS is based on the conventional 2nd-order lead-lag compensator. Accordingly, it is easy to implement in real systems. The damping effects and robustness of the proposed PSS have been evaluated in the two areas four machines power system with wind farms. Simulation results confirm that the robustness of the proposed PSS is much superior to that of the CPSS against various uncertainties.
