With the help of FACTS controllers, it is possible to reduce real and reactive power losses in the power system. Location and type chosen should be proper and rating must be optimal for economical operation of the power system. In Order find suitable FACTS location more easily and with more flexibility, this paper presents a graphical user interface (GUI) based on a genetic algorithm(GA) and particle swarm optimization(PSO) which is able to find the optimal locations an sizing parameters of FACTS devices. Among various FACTS controllers Thyristor Controlled series capacitor(TCSC), Static Var Compensator(SVC), Unified Power Flow Controller(UPFC) are considered in this paper. To verify the effectiveness of proposed algorithm, studies are carried out on IEEE 30 bus systems, with single and double type FACTS controllers. It is clear from the results that loss minimization is highly sensitive to range of compensation. MATLAB coding is developed for the simulation.
