Multi-objective Coordinated Design of TCSC and SVC for improving transient stability
Owing to contradiction between different control objectives under the combined operating mode of different controllers,the coordination operation problem will be translated into multi-objective optimization problem.This thesis presents a global tuning procedure based on multi-objective self-adaptive evolutionary programming algorithm (MOSAEP) which introduces self-adaptive variation rules.The main objective of this algorithm,by minimizing target functions,is to simultaneously optimize pre-selected parameters of TCSC and SVC in coping with the complex nonlinear nature to maintain the power transmission and improve the voltage stability.A threemachine nine-bus power system equipped with the coordinated designed SVC and TCSC controllers is applied to demonstrate the efficiency and robustness of the tuning procedure presented.Simulation results validate the improvement of transient stability in an optimal and globally coordinated manner compared with separate designed controllers.
