Repositioning of electric distribution substations using fuzzy decision making

Abstract

Electric distribution substations have an important role in energy distribution management. This substations transfer energy from 20000 V to 400V in centre of consumption. More decision in utilizing of this substation is basically assert on one attribute and most of time some important aspects may be forget. In this paper, the analysis of is done by using fuzzy logic method (fuzzy multi criteria decision making and choose four basic attribute involving lose of energy, voltage profile, cost and beautification by selecting one residential site in Noshahr City of Mazandran, Iran plus another four possible alternatives. As in this study, the intention is to optimize the position of substation and at the same time suggesting on the extension and construction of a new substation. As to conclude of this study the decision will help the electric managers and designers to be able to get multi aspects of decision making and improve the design, locations and grid reconstruction of the distribution substations. © 2011 Published by Elsevier Ltd.
