An Analytical Approach for Optimal Capacitor Placement in a Distribution System to Minimizetotal Annual Cost

Abstract

In this paper, an analytical approach with a self-sorting algorithm is proposed for the optimal capacitor placement and sizing (OCPS) in a radial distribution system. Initially, Loss sensitivity factor (LSF) method is used to nominate the potential buses for the capacitor placement and then the self-sorting algorithm is applied to find the optimal rating of the capacitors. The objective is to minimize the total annual cost and power losses in a distribution system along with enhancement of voltage profile. For this purpose, IEEE 15,33 and 69 buses are considered to show the effectiveness of the proposed algorithm and the results are compared with the existing techniques in terms of voltage improvement, power losses minimization and total annual cost reduction.
