Abstract

The invention discloses a weight quantification method for an electric vehicle charging decision, and belongs to the field of electric vehicles. The weight quantification method for the electric vehicle charging decision comprises the steps that 1, a city is abstracted into a road network layer and a power grid layer, and nodes, edges and weights in a road network and a power grid are defined; 2,defining a road network topology method and a power grid topology method; defining a road network weight and a power grid weight; and step 3, quantizing and feeding back the weight to the user. Compared with the prior art, the method can effectively assist the user in deciding and planning automobile charging, effectively guide charging load transfer, optimize the overall running state of a city,reduce the average weight of a network and effectively relieve charging congestion.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a weight quantification method for charging decisions of electric vehicles. Background technique [0002] The particularity of electric vehicles is that they are not only means of transportation in the road network, but also have the attributes of electricity load in the grid. In addition to bringing traffic congestion to the road network, large-scale disorderly charging may also cause grid load overload. High, affecting safe and stable operation and other issues. Therefore, the problem of disorderly charging of large-scale electric vehicles needs to be solved urgently. [0003] However, most of the existing studies only regard electric vehicles as grid loads, ignoring their traffic attributes. With the development of contemporary communication technology, the city makes the power grid and the road network more closely interactive, and the real-time transmission of road network...
