Power system harmonics and oscillations are an inevitable phenomenon of the electrical system. Faults protection relaying operation can cause the oscillation to collapse the system. In order to damp these power system oscillations, different control methods and different devices are used. Flexible ac transmission systems (FACTS) technology is the newest way of improving power system operation controllability and power transfer limits which has been added in the stream with the progress in the field of power electronics devices. A number of researches had been done to find out the control schemes for performing the oscillation-damping task of UPFC. Here we propose a method based on Model predictive control (MPC) and using Bacterial Forging Algorithm (BFA) for modeling Unified Power Flow Controller. Modeling of UPFC is designed with its unique capability to control simultaneously real and reactive power flows on a transmission line as well as to regulate voltage at the bus where it is connected. Therefore this device create a remarkable quality impact on power system stability. UPFC with additional PI controller is used along with the UPFC main controller for this purpose. The simulation is carried out in MATLAB/simulink which shows promising results.
