A Multi-objective Optimization Approach to Allocate Battery and Capacitor in Distribution Network

摘要

As the complexities of electrical power distribution network increases due to application of intermittent local generation and critical loads, power management in the network has become a highly challenging task. This paper is intended to investigate the opportunity of coalesce application of battery energy storage (BES) and capacitor unit in electrical distribution network. In this regard, a comprehensive multiobjective planning model has been proposed here to identify prospective connection points and capacity of BES and capacitor units in distribution network. Multi-objective particle swarm optimization (MOPSO) based solution algorithm having fuzzy decision making criteria is employed to get optimal solution after trade-off between the objective of extension economic margin and reliability satisfying wide range of operational factors. The efficacy of the solution algorithm has been verified on a 28-bus Indian distribution system.
