Strict-Tabu based eigenvalue optimization of power system stabilizer

Abstract

A Strict-Tabu (S-Tabu) optimization of power system stabilizer (PSS) parameters has been developed and presented in this paper. To achieve good damping characteristics over a wide range of operating conditions, S-Tabu is used to search for the best eigenvalue of the PSS and later installed into the phase lead-lag controller. The implementation studies are carried out on both single-machine, infinite-bus, and multimachine power systems, respectively. Simulation studies for a variety of disturbances on the power system with optimized PSS demonstrate its effectiveness in improving system performance. Comparison studies are also performed to show the advantages of the proposed controller over the nonoptimized Conventional PSS (CPSS). Copyright © 2000 Taylor & Francis.
