A Novel Technique for Optimal Allocation of RDG Units on Distribution Network

Abstract

Installation of Renewable Distributed Generation (RDG) units into distribution grids are present the better solution for meeting the increasing demand for energy in the world. The RDG units are connected consumer side for ameliorating voltage profile and mitigating loss in grid. The integration of RDG units in non-proper allocation will lead to more power loss and lower voltages, leading to higher operating costs in power grids. So, RDG units should be installed at optimal bus position with proper size. In this article, a novel Dolphin Echolocation Optimization (DEO) is presented to get optimal siting and sizing of RDG units simultaneously for diminishing power loss and ameliorating profile of voltage in the grid. The ability and robustness of the DEO is checked on IEEE-33 bus. The comparison with presented Genetic Algorithm (GA) and some recent literature works is done to affirm the efficacy and superiority of DEO technique. The simulation results have shown that DEO is the finest economical algorithm for finding the optimum positioning of RDG, leading to substantial loss mitigation and boost voltage profile compared to GA and other recent works.
