Abstract: Abstract:The distributed power generation technology is known as a most probable and most effective way to solve the future energy crisis of human society. Considering the feasible solution, the optimal solution of the network and other aspects, the influence of access of distributed power sources on the distribution network reconstruction was analyzed, and the reconstruction of the distribution network containing distributed power sources was realized. Simultaneously, the algorithm for reconstruction of distribution network was studied. Based on the differential evolutionary algorithm, an improved algorithm was proposed, and the improved algorithm was compared and verified on IEEE33 standard example. The result shows that the improved differential evolutionary algorithm has higher calculation efficiency and better global optimization ability comparing with the original differential evolutionary algorithm.
