The optimal Rearrangement of Distribution Systems by using Metaheuristic Optimal Methods

Load imbalance, multiple outages, high voltage drop and high losses are one of the major problems in distribution networks. One of the solutions to solving these issues today is to rearrange the distribution networks. The rearrangement of distribution systems can have different goals. Most researchers have considered reducing losses, balancing the load of feeders, and improving the voltage profile as the main objectives of the rearrangement. In the last decade, many methods have been used for rearranging, which have been remarkably used the heuristic and meta-heuristic methods. In this paper, an optimal rearrangement of the distribution system is carried out using the Particle Swarm Optimization (PSO) algorithm, inspired by the collective movement of birds. The results of simulation in MATLAB indicate the effectiveness of the proposed approach to reduce losses, improves the voltage profile and load balancing.
