Queuing theory algorithm based electric vehicle power change station's location choosing and planning method

Abstract

A method for site selection and planning of electric vehicle swapping stations based on queuing theory, the purpose of which is to realize rational planning and energy saving of electric vehicle infrastructure in urban areas. The number of facilities, taking the power station and centralized charging station (substation) as the overall research object, constructing an optimization model aiming at minimizing the overall operating cost and transportation cost, and finally using this model to realize the location planning of the electric vehicle power station. The invention plans and formulates a site selection model that meets urban construction requirements on the basis of fully considering the construction cost of the power station, transportation energy consumption, and user electricity demand. The experimental results prove that this method can not only calculate the optimal scheme for the site selection of the substation, but also obtain the optimal substation access scheme, which has an important guiding role in the planning and construction of electric vehicle charging and swapping stations in urban areas.

Description

technical field [0001] The invention relates to a method capable of rationally planning the site selection of an electric vehicle replacement station (charging and replacement station) in an urban area, and belongs to the technical field of power transmission and distribution. Background technique [0002] As an important non-renewable energy source, its distribution and storage largely affect changes in the world economy, so it has long been listed as a strategic reserve resource by various countries around the world. With the rapid development of the world's transportation industry, diversified transportation methods not only provide good protection for people's lives, but also greatly accelerate the consumption of oil energy, and lead to the emergence of energy crisis problems. The air pollution and greenhouse effect caused by vehicles in the process of driving are constantly testing the pollution control capabilities of governments in various countries. Among them, the ...

AI Technical Summary

Problems solved by technology

[0003] In the existing references, most of the research on electric vehicle infrastructure construction focuses on the site selection principles of charging stations, business operation models, and investment costs. Research out a planning scheme that meets the needs of multiple parties

At the same time, the research on the scale of charging and swapping stations in different regions is ignored, which leads to waste of construction costs

Therefore, the existing literature has limitations in varying degrees in the research on electric vehicle charging stations, and it is impossible to reasonably plan the construction of electric vehicle infrastructure in urban areas.
