Electric vehicle quick charging demand scheduling method based on load space transfer

Abstract

An electric vehicle rapid charging demand scheduling method based on load space transfer comprises the steps of dynamically selecting a path of an urban road network and sequentially establishing a road section dynamic travel time model and a dynamic path selection model; establishing a charging navigation scheme considering the congestion degree of the charging station, wherein a user charging navigation model, a charging station group service capability optimization model and a charging selection model considering vehicle decision dynamic evolution are sequentially established; and establishing an ordered rapid charging strategy based on the interaction between the charging station and the electric vehicle, including formulating the cost of the charging station and establishing a master-slave game model of the charging station and the electric vehicle. Factors such as interaction influence of multi-vehicle charging selection and non-uniform facility utilization rate of the urban fastcharging station are considered in the electric vehicle fast charging demand scheduling process; the interactive influence of charging station selection and path selection between vehicles and the interactive game strategy between stations and vehicles are fully considered, and a more scientific and effective scheduling scheme can be provided for quick charging of electric vehicles.

Description

technical field [0001] The invention relates to a method for dispatching fast charging demand of an electric vehicle. In particular, it relates to a fast charging demand scheduling method for electric vehicles based on load space transfer. Background technique [0002] Under the background that countries around the world have introduced policies to ban the sale of fuel vehicles, electric vehicles will rapidly become popular as an alternative. Electric vehicles running on the road usually choose fast charging when replenishing electric energy. Large-scale disorderly charging will cause serious congestion at some charging stations and increase the burden on the power grid. Therefore, it is particularly important to reasonably dispatch vehicles that need fast charging. [0003] At present, some research has been done at home and abroad on the fast charging demand dispatching of urban electric vehicles. However, judging from the current status of fast charging guidance for ele...

AI Technical Summary

Problems solved by technology

Since the formulation of fast charging station service fees fails to take into account its negative impact on charging demand, it may cause the problem of unbalanced utilization rates of charging stations in the region due to lack of reasonable distribution of charging demand. At the same time, such a solution is more It is difficult to adapt to the technical requirements of demand response in guiding charging behavior

[0004] Aiming at the limitations of the traditional fast charging scheduling method for electric vehicles, the present invention proposes a fast charging demand scheduling method for electric vehicles based on load space transfer, which fully considers the interaction of charging station selection and path selection between vehicles and the station-vehicle The interactive game strategy between them can provide a more scientific and effective scheduling scheme for the fast charging of electric vehicles
