Coordination of PSS and TCSC controller using modified particle swarm optimization algorithm to improve power system dynamic performance

摘要

This paper develops a modified optimization procedure for coordination of a power system stabilizer （PSS） and a thyristor controlled series compensator （TCSC） controller to enhance the power system small signal stability.The new approach employs eigenvalue-based and time-domain simulation based objective functions simultaneously to improve the optimization convergence rate.A modified particle swarm optimization （MPSO） algorithm is used as the optimization algorithm.The results of simulations and eigenvalue analysis for a single machine infinite bus （SMIB） system equipped with the proposed PSS and TCSC controllers confirm that the new approach is effective in enhancing the system stability.
