Embodiment Construction

[0015] specific implementation plan

[0016] Taking a 25-node traffic network as an example, a detailed algorithm description is given below, and a series of experiments prove the effectiveness of the proposed method.

[0017] Step (1), obtain the topological structure model of the traffic network in the city; Described topological structure model comprises the weight coefficient W of all traffic network nodes, and the actual distance d between every two adjacent nodes ij ; Among them, the weight coefficient W of traffic network node i i The larger the value, the greater the traffic congestion of the node, that is, the more vehicles passing through the node; the specific parameters are as follows: figure 1 As shown, the figure uses a scale of 1:18Km.

[0018] Step (2), survey the total number of electric vehicles in the cities studied by the Institute of Statistics

[0019] Step (3), according to the topology model of the traffic network obtained in step (1), use the grav...

Abstract

The invention discloses an optimal location planning method for electric vehicle fast-charging stations in a city distribution network. By analyzing the factors such as the busy degree of a road network in a city, taking the minimum sum of the distances by which all the electric vehicles reach the nearest fast-charging stations as the optimal objective, the optimal locations of the fast-charging stations can be obtained through solving, which can save the distance costs of charging of the electric vehicles and facilitate the charging of the electric vehicles.

Description

technical field [0001] The invention relates to the problem of site selection and planning of fast charging stations for electric vehicles, in particular to a method for optimal site selection and planning of fast charging stations for electric vehicles in urban power distribution networks. Background technique [0002] With the rapid development of the economy, the problems of resource scarcity and environmental pollution are becoming more and more serious. The current huge automobile market is exacerbating the consumption of resources and adding more pressure to the urban environment. Electric vehicles are becoming the main development direction of the automobile industry because of their energy-saving and environmental protection features. With the support of national policies and the active participation of major automobile manufacturers, the technical level of electric vehicles is increasing day by day. At present, some electric vehicle products have been formed and p...
