In order to improve the economy of distribution network operation and the reliability of power supply, the system average outage frequency and the system average outage duration are selected to represent the power supply reliability of the distribution network in this study, and the active power loss factor is considered at the same time, a multi-objective reconstruction model of distribution network is established, which takes the power supply reliability index into account. This study introduces quantum theory and Metropolis criterion into artificial swarm algorithm, and the optimal solution of multi-objective reconstruction model is determined by fuzzy satisfaction decision method, a multi-objective reconstruction model optimization method for distribution network based on improved artificial swarm algorithm is proposed. The distribution network reconstruction example simulation system established, and the feasibility and superiority of the reconstruction model and solution method are verified by comparison with other intelligent methods.
