Electric vehicle charging station dynamic planning method considering charging demand growth

Abstract

The invention discloses an electric vehicle charging station dynamic planning method considering charging demand growth. The method comprises the steps of firstly, introducing a charging station static planning method which does not consider an electric vehicle holding amount, and adopting a self-adaptive particle swarm algorithm, thereby obtaining a planning scheme of Nmax charging stations underthe situation of the high electric vehicle holding amount; and then, in an initial stage of dynamic planning, taking the Nmax charging stations as candidate stations, selectively building new charging stations to meet the charging demands of users and minimize the investment cost of the charging stations, and along with the increase of the electric vehicle holding amount and the charging demands,according to a certain period, and expanding the existing charging stations or selectively building the new charging stations in the remaining candidate stations on the basis of the existing chargingstations. Research results show that the method can meet the charging requirements at different moments along with the change of the electric vehicle holding amount. The method provided by the invention not only considers the increase of the electric vehicle holding amount but also is superior to a method for continuous updating of planning on the basis of a traditional static planning model.

Description

technical field [0001] The invention relates to a dynamic planning method for an electric vehicle charging station considering the increase in charging demand, and belongs to the technical field of electric vehicle charging station planning. Background technique [0002] With the increasingly prominent problems of energy shortage and environmental pollution, electric vehicles have attracted widespread attention due to their good environmental and social benefits such as zero exhaust emissions and low noise pollution. France, the Netherlands, Germany and other countries have proposed plans to stop selling fuel vehicles, and my country has also started research on the exit schedule of traditional fuel vehicles. The rational planning and construction of charging infrastructure is an important guarantee for the large-scale promotion of electric vehicles, and it is an urgent task to accelerate the promotion of electric vehicles. [0003] At present, many scholars at home and abr...

Problems solved by technology

The accessibility and convenience of charging infrastructure is the basis for the large-scale promotion of electric vehicles. However, building charging stations too far ahead of time in order to promote electric vehicles will lead to a series of problems: the construction of charging stations requires a lot of investment, but the existing electric vehicles Under the background of low retention level, it is difficult to recover the cost in the short term, the rate of return is low, and it is not attractive to investors; on the other hand, the current electric vehicle battery technology and charging technology are not yet mature, and the charging infrastructure standard specification system It is not yet perfect, and a mature business model has not yet been formed. At this stage, excessive planning of charging stations will lead to idle charging stations, high depreciation costs and high operation and maintenance costs, and more importantly, it is not conducive to the use of new charging facilities in the future and the existing charging Upgrading and updating of facilities
