Multiple Distribution Generation Location in Reconfigured Radial Distribution System Distributed generation in Distribution System

Abstract

Distribution system reconfiguration is one of the major approaches to reduce the losses in the distribution system. With the integration of Distributed Generation (DG) in distribution system, there can be further improvement in voltage profile and further loss reduction in the reconfigured system. The main contribution of this paper is: (i). Proposing novel and modified novel power loss sensitivity methods for finding optimal locations for placement of multiple DGs, (ii) obtaining the sizes of distributed sources for reduced losses and better voltage profile, and (iii) Study of variation of multiple DG sizes taking the effect of reconfiguration of the distribution system, (iv) Study of the impact of DG sizes taking into consideration the power factor. The proposed method has been implemented and tested on IEEE 33 bus distribution system.
