This paper investigates an approach that determines the desired locations of capacitors in a radial distribution system to improve voltage profile and reduce active power losses. Capacitor placements are done by power loss index and loss sensitivity factors. Loss Sensitivity Factors provide relevant information about the sequence of potential nodes for capacitor placement. In this paper load flow of pre-compensated distribution system is carried out. On the basis of load flow solutions, loss sensitivity factors (LSF) and power loss indices (PLI) indicating the potential locations for compensation are computed. From LSF and PLI, the candidate number of buses is identified for the placement of the capacitor. The proposed approach to find the locations of the capacitor placement by two different methods is tested on IEEE 34 & 69 bus radial distribution system and the net benefits were compared by utilizing these methods.
