Research On Regional Site Selection And Layout Of Electric Heavy Truck Charging And Battery Swapping Station Project

In recent years,electric heavy truck has been paid great attention by China’s transportation industry for its zero-emission,pollution-free and economical characteristics of new energy vehicles.Charging and battery swapping stations are important basic facilities for electric heavy trucks to supplement electric energy.Whether the site selection and layout of charging and battery swapping stations are reasonable in the early stage will directly affect the operating benefits of electric heavy trucks in the region and the further promotion of electric heavy trucks in China.Research on the site selection of electric heavy truck charging and battery swapping station plays a very important role in urban economic development,rational utilization of resources,urban energy conservation and emission reduction,and popularization of electric heavy truck.Aiming at the above topics,based on the related research theories of location set coverage,this paper proposed an improved set coverage model applicable to regional site selection layout of electric heavy truck charging and battery swapping station through literature research method,qualitative and quantitative analysis method,mathematical modeling,empirical analysis and other methods.It can analyze the planning layout of electric heavy truck charging and battery swapping station in a certain area and get the optimal scale and location.Firstly,cubic exponential smoothing method and logistic growth function are used to predict the holding capacity of electric heavy truck.Then,consider the factors affecting electric heavy card working scene,combined with the characteristics of the topography and fill in the location of the power plant construction costs,operational costs,operating earnings to evaluate economic indicators,such as charge for electricity demand as constraint conditions,the minimum total cost as the objective function,build based on the improved set covering model in power station location planning model,The improved genetic algorithm is used to solve the problem.Finally,through practical site selection in Hebei Province and sand table simulation,the solution results show that the model can optimize the site selection of electric heavy truck charging and battery swapping station in the region,and has a certain rationality and feasibility.Driven by national policies and industry changes,electric heavy truck charging and battery swapping station is bound to be an important component of new infrastructure in the future.Reasonable site selection and layout will be an important topic for industry development.It is hoped that the research content of this paper can play a positive role in the development of the industry.
