Reconfiguration of Distributed Power Distribution Networks Based on Gravitational Search Algorithms

Abstract

Distributed power supply access to the system affects the tidal distribution of the distribution network. The article establishes a mathematical optimization model with network loss minimization and load balance minimization as the objective function. In this paper, the idea of elite strategy is introduced into the gravitational search algorithm and combined with the Sigmoid function, an optimization method of distribution network reconfiguration based on the improved gravitational search algorithm is proposed by improving the particle iteration rule. The mathematical model is solved using the improved algorithm, and the results show that the net loss and load balance of the system is reduced after the distribution network reconfiguration. The simulation results verify the effectiveness and feasibility of the proposed method, which has a strong global optimization capability and fast convergence.
