Comparison of GA & PSO in UPFC in A 39 Bus Network

R. Revathi, J. Shervy Haeden

Abstract: In this Paper, the IEEE39 bus system is taken with problem parameters voltage stability, position of placing UPFC and the angle of series voltage injection. These parameters are determined with reference to IEEE39 bus values and power flow calculations are done in MATLAB. Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) is done to find the best position maximum stability and series injection and the best optimization among the both is compared.
