Distribution Network Reconfiguration Basedl on Modified Particle Swarm Optimization Algorithm

As a non-liner optimal problem, distribution network reconfiguration (DNR) impacts on economic benefit of power system greatly. In this paper, a modified particle swarm algorithm (MPSO) has been presented to solve the complex optimization problem. In the MPSO algorithm, the particles are initialized with chaos optimization method in its sub-area, which reduces the influence caused by the particle's initial position. The mean optimum of individual is introduced, which makes one particle acquire more information to adjust its movement. Finally, we propose the method which uses MPSO algorithm to solve DNR problem. The numeric simulation for IEEE 69-bus system shows that MPSO algorithm is feasible to solve DNR problem
