Biogeography based Optimization for Multi-Objective Reconfiguration Problem in Distribution Networks

Abstract

Background/Objectives: The focus of this article is to develop a new strategy for solving multi objective reconfiguration problem with a aim of obtaining the global best solution. Methods/Statistical Analysis: The traditional solution methods for reconfiguration may not provide the global best solution. Besides they may not handle non differentiable objective and constraint functions. Recently a Biogeography based Optimization (BBO). A method of meta Heuristic optimization has been outlined for solving optimization problems. This paper develops an effective method using BBO for solving reconfiguration problem with objectives of loss minimization, voltage profile enhancement and voltage stability improvement. Findings: The results of IEEE 33 and 69 node networks indicate that the proposed method is able to provide better solutions than the existing methods. Application/Improvement: The method can be applied in distribution automation systems for online operations. It can be further improved by combining the BBO with Heuristic rules for enhancing the research process.
