International Journal of Engineering and Information Systems (IJEAIS)   Year: 2021 | Volume: 5 | Issue: 2 | Page No.: 157-159 Improvement Performance Of Radial Distribution System By Optimal Placement Of Photovoltaic Array Jalilov Urinboy, Hasanov Mansur Abstract: This article presents the performance improvement of a Radial Distribution System (RDS) by optimally placing a photovoltaic (PV) array using a Differential Evolution (DE) algorithm. This article aims to reduce real power losses, improve the voltage profile (VP). The result showed that the optimal placement of the photovoltaic array is more efficient. The test system reviewed here is a standard 33 bus system. The proposed approach was implemented in the MATLAB software.
