In this paper, the UPFC injection model is used to investigate its effect on load flow and loss reduction in power systems. In this study, the Newton-Raphson algorithm is modified to consider the benefits of having a UPFC in the power system. Simulations have been implemented in MATLAB and the IEEE 14-bus system has been used as a case study. Simulations investigate the effect of injecting a series voltage with various magnitude and phase characteristics on the power flow of the system. It also considers the effect of the parallel branch on the voltage of the related bus. Finally, the optimum place for installing a UPFC, in order to have minimum loss in the system, is suggested based on the simulation results and the structure of the power system.
