Abstract

Present-day power system has highly complex and stressed operating condition owing to insufficient reactive power for meeting the required power demand. This increases the real power and reactive power losses and voltage instability that occurs in a power system. To attain the malleable operation of the power system, FACTS (Flexible Alternating Current Transmission System) devices have been used. Optimal location of FACTS devices influences the performance of the system and majorly affects the line/bus reactive power flows and hence with this effect, the line/bus voltage profiles has been improved and further the power losses are reduced. Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and GAPSO Hybrid methods have been used for identifying the weakest bus/branch for suitable placement of UPFC device to improve the voltage stability. More significant reduction of the power losses in a MATLAB environment have been discussed in this paper.
