Electric vehicle charging path optimization method giving consideration to power grid load balance and user experience

Abstract

The invention discloses an electric vehicle charging path optimization method giving consideration to power grid load balance and user experience. The method comprises the steps of: S1, obtaining the current residual electric quantity and the minimum residual electric quantity of a vehicle-mounted battery on an ith electric vehicle, and the starting point and the destination of the electric vehicle, and calculating the charging demand of the electric vehicle user according to the current residual electric quantity, the minimum residual electric quantity, the starting point and the destination; S2, if the electric vehicle user has a charging demand, calculating an electric vehicle charging path with the shortest distance priority to obtain an electric vehicle charging path with the shortest driving distance; S3, calculating driving time from the starting point to the charging pile of the electric vehicle, queuing time, charging time of the electric vehicle and available time of the charging pile in the charging station, and obtaining total time of the electric vehicle of the charging path with the shortest distance priority; and S4, by taking the minimum total duration of electric vehicles under the charging paths with the shortest distance priority of all electric vehicles as an objective function, constructing power grid charging load balance and electric vehicle user experience constraints, and carrying out charging path optimization.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging path optimization and intelligent guidance, in particular to an electric vehicle charging path optimization method that takes into account both grid load balance and user experience. Background technique [0002] With the increasingly prominent problems of energy shortage, global warming, and ecological environment deterioration, it is imminent to build a clean, low-carbon, safe and efficient modern energy system. In terms of transportation energy, automobile products mainly consume non-renewable fossil fuels such as oil and natural gas, and are major emitters of carbon dioxide. As an important type of new energy vehicles, electric vehicles have high energy efficiency and no mobile exhaust emissions. They are an environmentally friendly means of transportation. Therefore, increasing the proportion of electric vehicles in transportation energy consumption is an important measure ...

AI Technical Summary

Problems solved by technology

[0005] At present, the charging path optimization method for electric vehicles only considers the minimum overall time, fails to consider the balance of the grid load, and there is a risk of poor experience for individual users when optimizing the overall electric vehicle charging path
