Enhancing Quality Control Power System Stability Controller Using Design Theory Optimal RH-∞

This paper presents design methods of the power system stabilizer (PSS) by RH-∞ optimization theory to improve the quality of the power system stability. PSS controller design is optimized in terms of parameters and structure. Techniques solve the problem optimal RH-∞ here is done through solve the problem modell maching. Matlab simulation results clearly show the effectiveness of this controller compared with the traditional PSS controllers, especially in reducing low-frequency oscillations of the power system (LFOs).
