Multiple distributed generations placement and sizing based on voltage stability index and power loss minimization

Abstract

This paper proposes a rapid analytical method to determine the locations and sizes of multiple distributedgenerations (DGs) inside a distribution network. DGs’ locations are chosen with the aim of enhancing voltage stabilityand their sizes are picked so as to minimize system power losses. To evaluate the effect of the DG’s nature on thesystem’s performance, the proposed DG allocation method is tested for all DG types and the impact of the combinationof different types of DGs is equally investigated, which offers a guide to designing an optimal hybrid network.
