This paper presents the influence of UPFC to increase transfer capacity and augment transmission security in unit commitment problem. Some effects of using FACTS devices are to increase transmission capability and control power flow. In the overloaded lines, the problem will be solved without UPFC and with UPFC considering transmission constraints. Using Benders decomposition, the formulation is decomposed into a master problem and a subproblem. The master problem without transmission constraints is solved using priority list method. In the case of transmission flow infeasibility, Benders cuts are produced for unit commitment rescheduling. Installation of UPFC reduces cost and considers transmission constraints. Problem formulation, representation and the simulation results for 6 generator in the 26 bus network is tested and influence of UPFC is investigated.
