This paper presents a performance enhancement of a radial distribution system using simultaneous reconfiguration, optimal placement of DSTATCOM and PV array using differential evolution algorithm (DE).The purpose of this paper is to reduce real power loss, improved voltage profile (VP), increased load balance (LB).Here result proved that simultaneous reconfiguration along with optimal placement of DSTATCOM and PV array is more efficient than Single objective optimization. Also the results obtained from differential evolution algorithm (DE) are more efficient than other method. The test system considered here is IEEE 33 bus system. This proposed approach was implemented in MATLAB software.
