In this study, the problem of clean energy output power dissipation in distribution network with DG in invertigated. The multi-objective cooperative game is used to reconstruct the distribution network in each period. A multi-objective dynamic reconstruction model is established on the basis of cooperative games with multiple reconstruction targets as players. The model is solved by the route exchange method of the drosophila optimization algorithm improved by the idea of simulated annealing method to obtain the optimal solution in each time period, and then the most dynamic reconstruction scheme of the research object is obtained according to the time period division.The IEEE33-node power distribution system including wind power station and photovoltaic power station is simulated, and the optimal dynamic reconfiguration scheme of power distribution network considering both operation cost and clean energy utilization rate is obtained. During the whole reconfiguration process, only 14 actions are taken, the network loss is reduced by 31% and the DG consumption is increased by 115%, which verifies the effectiveness of the proposed mathematical model and solution scheme.
