Remote power system stabilizer tuning using synchrophasor data

Abstract

Power system stabilizer (PSS) tuning is an important and challenging task in today's power system. In order to investigate the use of remote measurements of generator speed signals in respective PSS tuning, data from phasor measurement units (PMUs) are used in this paper. The PSSs parameter remote tuning is illustrated using a real-time digital simulator (RTDS). A MATLAB-based particle swarm optimization (PSO) algorithm is implemented including the interface with the RTDS system. The two-area four-machine power system benchmark is simulated, and speed signals obtained from PMUs are used in the tuning process. The best parameters obtained for PSSs and typical results are presented to show the effectiveness of using PMU measurements for remote tuning of a number of PSSs.
