This paper addresses a control methodology to enhance power system dynamic stability and voltage regulation by augmenting existing generator controls (conventional PSS and AVR) using an optimal static gain vector. The control design problem is reduced to finding a new control loop including a simple fixed gain vector. In order to optimal tune gain elements, the problem is formulated via an Hinf static output feedback (Hinf-SOF) control technique, and the solution is easily found using an iterative linear matrix inequalities (ILMI)algorithm. Real-time experiments have been performed for a longitudinal four-machine infinite-bus system on the Analog Power System Simulator at the Research Laboratory of the Kyushu Electric Power Co. The proposed robust technique is shown to maintain the robust performance and minimize the effects of disturbances.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
