Strategy for the control of multiple series compensators in the enhancement of interconnected power system stability

A multiple controlled series compensator (CSC) control strategy to enhance power system stability is presented. The proposed control strategy consists of three different stages, each of which has a different purpose and approach. The effectiveness of the proposed control strategy is tested on a multimachine power system associated with two CSCs. Computer simulation results indicate that CSC regulation using the proposed control strategy can reinforce power system stability.
