A charging station location method considering the traffic running state of an urban road network

Abstract

The invention discloses a charging station location method considering the traffic running state of an urban road network, comprising the following steps of S1 obtaining the OD travel data of the region, the vehicle holding quantity and the electric vehicle proportion, the distribution law of the initial electric quantity and the charging electric quantity, establishing the regional road network diagram, considering the traffic running state of the road network, and carrying out VISSIM dynamic traffic assignment simulation to obtain the vehicle traveling track, speed and distance data; 2 assigning an initial electric quantity and a charging electric quantity to each vehicle, and combining that data of the vehicle travel track, the speed and the distance, screening and obtaining the distribution of the demand point in the area; 3 aiming at minimizing that construction and operation cost of the regional builder and the detour cost of the user, and taking the charging demand of the user as a constraint condition, and obtaining the optimal quantity of the char station construction; S4 determining the final location of the regional charging station according to the distribution of the regional demand points and the optimal number of charging stations. This method provides a reference for the determination of the number and location of charging stations, and has practical significance.

Description

technical field [0001] The invention relates to the field of urban traffic planning and optimization, in particular to a method for selecting the location of a charging station considering the traffic operation status of an urban road network. Background technique [0002] Concerns about air pollution, energy dependence and growing climate change motivate us to find new transportation solutions. Due to environmental and economic reasons, countries are turning to clean and environmentally friendly electric vehicles. Electric vehicles (BEV) refer to vehicles powered by vehicle-mounted power supplies and motor-driven wheels that meet the requirements of road traffic and safety regulations. They can effectively relieve environmental pressure and have broad application prospects. [0003] Charging stations are an important element in the infrastructure that provides electric energy for electric vehicles. With the continuous growth of electric vehicles, there is an increasing dem...

Problems solved by technology

Due to the high construction cost of charging stations, the current penetration rate of electric vehicles is low, and the utilization rate of charging stations is low, making the scale and layout of charging station facilities far behind the rapid development of electric vehicles. Restricting the utilization rate of electric vehicles, how to reasonably arrange charging stations and determine the appropriate size has become a matter of great concern to traffic management departments, urban planning bureau power supply management departments and private investment companies

[0004] At present, domestic and foreign research on the location selection of electric vehicle charging stations mainly focuses on the optimal algorithm, mostly for the purpose of economy. Some scholars also consider the impact of the power supply system on the location selection, but rarely consider the traffic operation status of the road network. Impact on charging demand points
