Abstract

The invention discloses a method for locating and sizing an electric vehicle charging station. The method comprises the following steps: acquiring a regional road network structure diagram; respectively calculating the number of charging stations needing to be constructed in a regional road network, the traffic flow density of intersection nodes and the total charging quantity demand; establishinga site selection model, and solving the specific position of the charging station; establishing a charging queuing model, and optimizing the number configuration of charging piles in the charging station. According to the number of the charging stations needing to be built and the number of the charging piles in each station obtained through optimization, the total cost of the planning area is output; the user charging convenience and the charging pile utilization rate are improved, the number of charging piles in the station is optimized according to the charging queuing model, the utilization rate is increased, and the cost is reduced.

Description

technical field [0001] The invention relates to a method for site selection and capacity determination of an electric vehicle charging station, and belongs to the technical field of electric vehicle charging station planning. Background technique [0002] With the acceleration of urbanization, the problems of environmental pollution and resource shortage are becoming more and more serious, which restricts the rapid and healthy development of my country's economy. In order to encourage more users to use new energy vehicles, it is necessary to consider two aspects of the location of the charging station and the number of charging piles equipped in the charging station, so as to improve the convenience of charging for users and the efficiency of charging services. In the existing research on site selection and capacity determination of charging stations, the construction cost of charging stations, grid loss costs, and operating costs of charging stations are considered. Through...
