A NEW GA APPROACH FOR OPTIMAL CONTROL SETTING DETERMINATION OF UPFC IN POWER SYSTEM OPERATION

This paper presents a new, hybrid genetic algorithm (GA) approach to solve optimal power flow (OPF) in power system incorporating flexible AC transmission systems (FACTS). A versatile FACTS device, UPFC (unified power flow controller), is considered. In the solution process, GA, coupled with full AC power flow, selects the best regulation to minimize the total cost and keep the power flows within their security limits. The optimization process with GA is presented with case study examples using IEEE test system to demonstrate its applicability.The results are presented to show the feasibility and potential of this new approach
