The Optimal Reconfiguration of Power Distribution Networks for Power Quality Improvement Using Multi-Objective Planning

Power distribution networks as the interface between the power transmission networks and micro/macro consumers, are among the most important components of electrical energy systems. The main task of these networks can be considered as reducing the voltage level and preparing electrical energy for delivery to consumers, which is done according to different structures and voltage levels. An instance of extensive and important research in this area is the rearrangement of distribution networks. One of the effective optimization methods in network rearrangement is the use of heuristic algorithms in order to find the best arrangement for the distribution network by considering various network parameters and constraints. In this paper, while modeling the problem of optimal rearrangement of power distribution networks with the aim of improving power quality, the solution is also presented using both the single and multi-objective variants of the particle swarm optimization (PSO) algorithm. The simulation results show successful performance and suitable efficiency for both methods of single-objective and multi-objective PSO optimization.
