This paper presents the optimization of large-scale practical distorted distribution network for maximum losses reduction and voltage profile improvement based on two-stage methodology for capacitor placement problem. In the first stage, a fuzzy expert system (FES) is used to find the optimal capacitor locations, and in the second stage, a selective particle swarm optimization (SPSO) is used to find the optimal capacitor sizing. The problem is posed as an optimization problem with objective to minimize the total cost of power and energy losses and capacitor banks including constraints for bus voltage and total harmonic distortion (THD) limits. Simulation results show the benefits from optimization and the effect of harmonics on optimal capacitor placement.
