Optimizing configuration method for amount of chargers of electromobile charging station

Abstract

The invention relates to an optimizing configuration method for the amount of chargers of an electromobile charging station. The method comprises the following steps that (1) traffic flow of a selected charging station position is investigated, and the distribution relation between the traffic flow and time is analyzed; (2) a distribution rule of charging vehicles is extracted according to traffic flow information, and charging requirement of the fast charging station is calculated; (3) the mechanism service cost in unit time is calculated according to the construction cost, operation and maintenance cost, network loss cost and operation time limit of the fast charging station; (4) travel time of users of a city is used as waiting cost of the users; and (5) aimed at minimizing the expected value of the average total cost per day, the optimal amount of chargers of the charging station is calculated via a random service system model. Waiting cost and operation cost of the fast charging station are taken into full consideration during design, capacity configuration of the fast charging station can meet charging requirements of users, the service level is ensured, resources are optimized in configuration, and unnecessary waste is avoided.

Description

technical field [0001] The invention relates to the field of electric vehicle charging station planning, in particular to a method for optimally configuring the number of chargers in an electric vehicle fast charging station. Background technique [0002] With the rapid development of the economy, the problems of resource scarcity and environmental pollution are becoming more and more serious, and cars, as people's means of transportation, gradually penetrate into every household, and the total number of cars is also rising at a high speed, which makes resource and environmental problems worsened. Electric vehicles have attracted the attention of many countries and enterprises due to their energy-saving and environmental protection features. At present, the research and development of electric vehicle-related technologies is in full swing, the industrialization and commercialization model has basically taken shape, and some considerable products have been officially put int...

Problems solved by technology

However, due to the randomness of private car charging, it is difficult to determine the capacity configuration of fast charging stations for private car charging needs.

If the number of chargers is configured according to the charging demand during the peak period of traffic flow, it is easy to cause the charger to be idle most of the time, and the utilization rate is not high; Congestion, poor service
