Abstract

A new approach for designing power system stabilizers (PSS) in multimachine power systems is proposed. It is found that the sensitivity of PSS effect (SPE) defined earlier by the authors for PSS location selection is equal to the sensitivity of a mode with respect to the change of the PSS transfer function. The displacement of a system mode caused by the installation of a PSS can be predicted from the SPE. Based on this prediction the PSS location can be selected and the PSS parameters tuned. The proposed method has been used to design a PSS for a 13-machine power system to increase the damping of an interarea model. The time-domain simulation results indicate that the proposed method can predict the best PSS location to increase damping of the interarea mode. It is very simple to use SPE to tune PSS parameters
