In recent years, a huge impact is caused on the active distribution network by the increasing number of new energy vehicles based on electric vehicles and hydrogen vehicles and the large-scale access of new energy. An economic dispatch method of active distribution network considering the low-carbon economic benefits of new energy vehicles is proposed. Firstly, the operation framework of active distribution network with new energy vehicle access is constructed, and the operation model of multi-energy conversion equipment is established. Secondly, considering the schedulability of the multi-energy load demand on the load side of the distribution network, a response model is established to assist the grid-connected consumption of new energy. Then, by introducing new energy vehicles to replace fuel vehicles to solve the problems of new energy output difficulties and environmental pollution in the active distribution network, a new energy vehicle participation model in the carbon-green certificate market transaction is constructed to improve the economic benefits of the active distribution network. Finally, taking the minimum daily average total operating cost of active distribution network as the goal, the optimal scheduling model is constructed. Through the comparative analysis of different schemes, the positive effect of the proposed method on improving the economy, new energy consumption and low-carbon operation of active distribution network is verified.
