Comprehensive Cost Minimum Based Distribution Network Reconfiguration

The structures distribution networks are closed loops structure in the most cities, but when they are operating the loops will be opened. A method based on improved particle swarm optimization is proposed for distribution network reconfiguration with the objective of minimizing the comprehensive cost. Objective function is the sum of the distribution network losses cost, switches investment, the switching cost and the outage cost. An improved particle swarm algorithm is used in this paper. This new strategy can enhance the control response of the algorithm and conquer the premature convergence of the particle swarm algorithm. The switches operation numbers constraint is also disposed to avoid affecting the global optimality of programming. The improvement strategy for power distribution network reconfiguration can solve the infeasible solutions problem effectively.
