Voltage flicker and harmonics are some of the power quality problems which introduced to the power system as a result of nonlinear and stochastic behavior of arc furnaces operation. This paper investigates losses due to harmonics produced by an arc furnace on a network Using Particle swarm optimization. Preliminary results indicate that these losses are very small, but because of its expansion in all lines could reduce the power quality of entire network.
