摘要：Power-system stability improvement by shunt FACTS based damping controllers are thoroughly investigated in this paper. The present study considered both local and remote signals with associated time delays. The design problem of the proposed controller is formulated as an optimization problem, and differential evolution (DE) algorithm is employed to search for the optimal controller parameters. The performances of the proposed controllers are evaluated under different disturbances for both single-machine infinite bus power system and multi-machine power system. The performance of the proposed controllers with variations in the signal transmission delays has also been investigated. Simulation results are presented under various operating conditions and disturbances to show the effectiveness and robustness of the proposed approach.
