Distribution network reconfiguration for loss reduction using PSO method

Abstract

In recent years, the reconfiguration of the distribution network has been proclaimed as a method for realizing power savings, with virtually zero cost. The current trend is to design distribution networks with a mesh network structure, but to operate them radially. This is achieved by the establishment of an appropriate number of switchable branches which allow the realization of a radial configuration capable of supplying all of the normal defects in the box of permanent defect. The purpose of this article is to find an optimal reconfiguration using a Meta heuristic method, namely the particle swarm optimization method (PSO), to reduce active losses and voltage deviations by taking into account certain technical constraints. The validity of this method is tested on a 33-IEEE test network and the results obtained are compared with the results of basic load flow.

A Unified Power Quality Conditioner for Feeder Reconfiguration and Setting to Minimize the Power Loss and Improve Voltage Profile

“…e devices of distribution-FACTS are utilized to recover the problems of power in systems of distribution [1,2] that happen at a measure of milliseconds. In the mentioned time, D-FACTS has injected the active power and reactive power in the system to recover sensitive loads [9].…”

“…Improving voltage profile, balancing the load, and service restoration are some of the objectives mentioned in reconfiguration studies. In previous works, the heuristic model is proposed to obtain minimum loss configuration [1]. In [2], an innovative approach is provided for reducing losses and improving voltage profiles.…”

Optimal planning of RDGs in electrical distribution networks using hybrid SAPSO algorithm

“…PSO is used when the optimization problems have several solutions. In this algorithm the particles move in a bounded search space to find the overall best velocity and position depend on social experience of the swarm [22][23][24][25][26]. The value of the agent's velocity and its position of the swarm is updated as shown in Figure 2.…”

An effective network reconfiguration approach of radial distribution system for loss minimization and voltage profile improvement

“…Distribution networks have increased and spread too far, resulting in higher network losses and having less voltage control. Hence requirement of an effective and secure method of network reconfiguration is now most important and relevant [12]. In this paper, network reconfiguration is performed on radial distribution system (RDS) for loss reduction and improvement of voltage profile.…”
