A Study on the Optimal Parameter Selection of PSS Using Output Feedback

출력궤환에 의한 PSS의 최적계수 선정에 관한 연구

Since the late 1960s, the selection of the parameters of power system stabilizer (PSS) to damp out sustained low frequency oscillation of power generators in the steady state has been an active research area. This paper presents a new approach to select the optimal PSS parameters using the sensitivity of the quadratic performance with respect to the PSS parameters. The proposed algorithm has been applied to Seo-Cheon fossil power plant.
