Optimal location of UPFC devices for minimizing Losses in Transmission Line

Abstract

The fast increase in world loads has made electrical networks more complex and difficult to operate within their capacities. This has contributed to many issues like the failure of the loss of the power. Flexible alternating current transmission systems (FACTS) are therefore considered to be the best solution to this problem, the Unified Power Flow Controller (UPFC) device is the most important of FACTS devices because of its ability to reduce overall line losses and increase the power system's transmission capacity. To increase the advantages of this device we need to find the optimal location for it. In the search process code to determine the optimal placement of UPFC device to minimizing losses in the transmission line in the standard Institute of Electrical and Electronic Engineers (IEEE 14 bus) test system using Particle Swarm Optimization (PSO)by using (MATLAB program/M-file). This paper deals with the optimization of two UPFC compensator parameters in the power system with the aim of reducing losses and increasing the transmission line load limit by using a modified version of the PSO algorithm The power system simulation results show that the UPFC's optimal location has been able to minimize the losses from the transmission line.
