Abstract

This paper presents a new method for tuning the parameters of a conventional power system stabilizer. The region of acceptable performance for the stabilizer has been extended and covers a wider range of operating and system conditions, The parametric uncertainty in power systems has been handled using quantitative feedback theory (QFT), The required controller parameters are arrived at by solving an optimization problem that incorporates the control specifications. The robustness of the feedback controller has been investigated on a single machine infinite bus model and the results are shown to be consistent with the expected performance of the stabilizer.
