This paper presents an improved genetic algorithm (GA) to solve optimal power flow (OPF) problems in powersystem with flexible AC transmission systems (FACTS). Two types of FACTS' vices are considered. Thyristor controlledphase shifter (TCPS) and thyristor controlled series compensator (TCSC) are used to control power flow. In the solutionprocess. GA coupled with full AC power flow. selects the best regulation to minimize the total generation fuel cost and keepthe Power flows within their secure limits. The optimizavion process with GA is presented with case study examples of anIEEE test system to demonstrate its feasibility and effectiveness.
