Abstract

The invention discloses a charging station layout programming method based on a V-graph and an HS algorithm. The method comprises the steps of firstly, estimating the range of charging stations which are constructed in a programming area through anticipation of charging queuing waiting time; secondly, comprehensively considering multiple factors such as a charging requirement and a region characteristic, establishing a charging station layout programming object according to a charging station construction / operation cost, a charging on-the-way time consumption cost and an arrival-at-station queuing waiting time cost; and finally, randomly generating station address coordinates of the charging stations in the programming area, coding the station address coordinate for obtaining one-directional vectors, defining the service range of each charging station by means of a Voronoi-graph (the V-graph in short) and generating an initial harmony vector, calculating a solution by means of a harmony search (HS) algorithm and storing the solution in a harmony memory (HM), updating the harmony memory through studying the harmony memory and tone fine turning until a number of updating times of the harmony memory is reached, finding out a charging station layout programming objective value and determining an optimal charging station layout programming solution. The charging station layout programming method has advantages of effective integration of multiple factors and high calculating speed. Furthermore the charging station layout programming method can be used for finding out an optimal value.

Description

[0001] Technical field: [0002] The invention relates to a charging station layout planning method based on a V diagram and an HS algorithm, and belongs to the technical field of electric vehicle charging station layout planning. [0003] Background technique: [0004] Under the active guidance of government policies, the current number of electric vehicles has exceeded 500,000, and the promotion of electric vehicles will continue to accelerate. In order to meet the convenience of people's charging, it is necessary to build a complete charging facility to ensure the charging demand of electric vehicles. Charging stations are an important part of electric vehicle charging facilities and play an extremely important role. Therefore, it is necessary to rationally layout and plan the construction of charging stations to provide convenient and fast charging services for electric vehicle users. The existing charging station layout planning methods: first, there are too few consider...
