Method for planning electric vehicle charging stations in highway networks

Abstract

The invention discloses a method for planning electric vehicle charging stations in highway networks. The method comprises the following steps of: establishing a highway network model, wherein the highway network mode comprises a plurality of nodes and roads between adjacent nodes are called as sections; adding an initial node and a termination node in the highway network model according to an actual running distance of an electric vehicle when the electric vehicle reaches a highway network and a planned running distance of the electric vehicle when the electric vehicle leaves the highway network; adding a virtual section in the highway network model according to running journey constraint of the electric vehicle so as to obtain a highway network extended model, wherein the virtual section is the sum of distances of all the actual sections between two nodes; and establishing an electric vehicle charging station site selection and constant volume optimization model according to the highway network extended model, and solving the optimization model to output a charging station site selection and volume planning result. The method has the following advantages of optimizing the site selection and volumes of electric vehicle charging stations and reducing the investment cost of the electric vehicle charging stations under the premise of satisfying the charging demands of electric vehicles.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a planning method for electric vehicle charging stations in a highway network. Background technique [0002] In recent years, under the background of environmental pollution, increasing greenhouse benefits, and depletion of fossil energy, the potential of energy saving, environmental protection, and emission reduction of electric vehicles has been given good development prospects by countries all over the world. [0003] Electric vehicle charging facilities are a new type of urban infrastructure. Vigorously promoting the construction of charging infrastructure is conducive to solving the problem of electric vehicle charging and is an important guarantee for the development of the new energy vehicle industry. [0004] Electric vehicle charging facilities are a new type of infrastructure, and a mature planning method has not yet been formed at home and abroad. Unreasonab...
