Abstract:Conventional economic dispatching has been unable to meet the challenges of random access to renewable new energy and electric vehicles. In order to solve the problem of increasing the number of electric vehicles connected to the distribution network and the problem of grid connection of distributed power sources. In this paper, a detailed analysis of the intelligent dispatching network with electric vehicles is carried out. Firstly, the impact of electric vehicle access on the power grid is briefly analyzed. Secondly, this paper analyzes the coordinated optimization and dispatching of electric vehicles and smart distribution networks from four aspects: the types of electric vehicles connected to the grid, the goals of electric vehicles participating in optimal scheduling, the optimization scheduling model and the optimization scheduling modeling methods. From the analysis of the results of the optimized scheduling, it can be seen that considering the electric vehicle into the optimal dispatching of the intelligent distribution network can effectively reduce the operating cost of the distribution network, reduce the charging cost of the vehicle owner, and improve the utilization rate of the distributed power source. Then it briefly introduces the application of big data technology in intelligent distribution network optimization. Finally, the prospect of coordinated optimization and scheduling of electric vehicles and smart distribution networks is put forward.
