This paper concerns the Optimal Power Flow [OPF] in multi machine Power System with UPFC using Genetic Algorithm [GA]. The objective is to minimize the cost of the power system, to enhance the power flow in transmission lines and to maintain the voltages at the buses using UPFC. Using the proposed method, the optimal cost and real power losses of the power system with UPFC is achieved by developing a simple Genetic Algorithm and the location and rating of UPFC is also achieved by Newton Raphson's load flow method. IEEE 9 bus system has been studied to show the effectiveness.
