Abstract

In this paper, the concept of simultaneous tuning of static synchronous series compensators and multi-band power system stabilizers for damping out sub-synchronous resonances in a series compensated power system is presented. To achieve an effective damping effect, a supplementary sub-synchronous damping controller is added to the static synchronous series compensator. The teaching-learning-based optimization algorithm is employed for the simultaneous adjustment of the parameters of both the supplementary sub-synchronous damping controller and the power system stabilizer. The proposed method is executed on the IEEE Benchmark system and simulation results are provided to verify its capability in removing sub-synchronous resonances and maintaining the stability of the underlying system.
