| With the increasingly serious environmental pollution and energy shortage,the development of new energy vehicles has become the focus of social concern.The government has increased the support for new energy vehicles,and automobile manufacturers have increased their research and development efforts.However,as more and more electric vehicles are put into the market,the problem of insufficient charging resources for electric vehicles becomes increasingly prominent.Driving electric cars to travel in rural areas has become a way for modern urban residents to relax on holidays and weekends.However,as most of the scenic spots of rural tourism are in less developed areas in rural areas,the infrastructure is not perfect,there are not many charging stations for electric vehicles for users to recharge.Therefore,it is important for the government and electric vehicles(EV)manufacturers to consider the characteristics of rural tourism behavior as the influencing factor for the layout of charging stations,which is conducive to promoting the development of rural tourism industry and strengthening rural revitalization,as well as meeting the charging needs of users and improving the satisfaction of EV users.Therefore,the government and electric vehicle manufacturers need to consider the reasonable layout and optimization of charging stations.The research work of this paper includes the following aspects.Firstly,combining with the concept of travel chain,the paper analyzes the travel characteristics of rural tourism.Different from normal weekday trips in urban areas,rural travel features include uneven time distribution,imperfect rural road construction,and the need to expand the power network for charging stations in rural construction,which are all issues to be considered in the construction of charging stations for electric vehicles.Based on the analysis of economic,traffic and electric power factors,this paper discusses the influence of different factors on the siting of charging stations.At the same time,considering the characteristics of rural tourism,this paper analyzes and summarizes the demand model of common EV charging stations,and proposes a method to predict the charging demand of EV considering rural tourism.The charging demand of rural tourism travel is increasing year by year,so it is of great significance to study the location of charging station for rural tourism travel.Secondly,this paper analyzes the rules of round-trip travel in rural tourism and studies the influence of different vehicle range on charging site selection in round-trip travel.Based on the charging demand of round-trip travel and the characteristics of rural travel and based on the interception site selection model and aiming at the maximum charging demand served,an EV site selection model considering the characteristics of rural travel was established in this paper.In order to study the different demands of different charging station construction subjects on site selection,a site selection model based on government construction perspective and a site selection model based on user experience were constructed under the site selection model of electric vehicle charging station considering rural tourism.For the site selection model based on government construction,the construction cost is mainly considered.For auto makers,the main concerns are operating costs and user experience.These two models respectively provide the location modeling ideas for the government to build charging stations and the automobile manufacturers to build their own charging stations.At the same time,according to the characteristics of round-trip travel,this paper proposes the method of solving the corresponding charging combination that meets the battery life demand and proposes the algorithm of models.Finally,taking the road network of Jiangsu province as an example,the model is analyzed with the actual data and the simulation example,and the validity of the algorithm in this paper is verified.Based on the analysis of the three site selection models proposed in this paper,the influence of vehicle range on the site selection layout of EV charging stations is analyzed.It is found that the greater the vehicle range is.the fewer charging stations need to meet user needs.Based on the model from the perspective of government construction,the paper studies the effect of the tradeoff coefficient and different road network conditions on the site selection results.For the model based on user experience,the influence of different road network conditions and detour costs on site selection was analyzed.Compared with the complex urban road network,the sparse rural road network needs to build more charging stations to meet the charging demand.It can be concluded from the analysis that the government should pay more attention to the control of construction cost by increasing the effective radiation range of each point and controlling the cost as far as possible under the guarantee of service level.As for automobile manufacturers,they need to pay more attention to the control of operating costs and the improvement of user satisfaction and should optimize the number of charging stations to reduce costs.At the same time,through the analysis of the solution results of two models based on government construction and user experience,the validity of the EV charging station location selection model considering the travel characteristics of rural tourism is verified.Considering the location of charging stations of rural tourism characteristics is of practical significance for the government in the layout of charging stations and the role of automobile manufacturers in the operation of charging stations. |
