Method for optimizing site selection of electric vehicle charging stations

Abstract

The invention discloses a method for optimizing the site selection of electric vehicle charging stations. The charging convenience of people who charge electric vehicles is considered through the constraint conditions of service radii of the charging stations, the initial positions of the charging stations are determined by optimizing the number of the charging stations according to the land usage of subareas, investment in the charging stations is preliminarily optimized, reasonable load distribution is performed on the basis of the property of a Voronoi diagram, the site selection is optimized in each Voronoi polygon by using investment and cost which can influence the site selection of the charging stations as optimization objectives, and the positions and service areas of the charging stations and the number of chargers in the charging stations are determined. Examples prove that the site selection of the charging stations can be quickly and effectively performed by the method, and requirements on charging convenience, economy and investment optimality are met.

Description

technical field [0001] The invention belongs to the technical field of site selection optimization for electric vehicle charging stations, and relates to a site selection method for electric vehicles based on Voronoi diagrams and map division theory, and using charging station investment and consumption costs as optimization models. Background technique [0002] Electric vehicles have the advantages of alleviating energy crisis, environmental pollution and improving the structure of the automobile industry. Therefore, they are strongly supported by the state and have broad development prospects. As a charging system for electric vehicle infrastructure, reasonable charging facility planning is not only related to the convenience and economy of consumers, but also affects the widespread promotion of electric vehicles and the sustainable development of the electric vehicle industry. Therefore, large-scale construction of charging facilities Before that, the method of rationally...

Problems solved by technology

For the location planning of electric vehicle charging stations, the minimization of charging station investment costs and consumer use costs should be considered first. For existing research, the main focus is on the optimization of electric vehicle charging station investment costs, while ignoring the use of consumers. Second, the convenience of charging for consumers is an important factor affecting the location of charging stations. This is because when consumers charge electric vehicles, they will first consider charging at the charging station closest to them. The site selection and scale of the charging station, but the existing research ignores this important factor; finally, the existing research focuses on the optimization algorithm of the model, and does not involve the specific location planning of the charging station in the entire region

[0004] In general, the existing planning methods for location selection of electric vehicle charging stations lack consideration factors, and there is no specific regional location planning.
