Forecasting of electric vehicle charging load in highway service areas considering meteorological factors
Weather has a significant impact on traffic flow,and the state of traffic flow directly affects the spatio-temporal distribution of electric vehicle charging load.In order to explore the impact of weather on the spatio-temporal distribution of electric vehicle charging load in highway service areas,a forecasting method of electric vehicle charging load in highway service areas considering meteorological factors is pro-posed.The factors causing mileage degradation during high-speed driving of electric vehicles are analyzed,and an energy consumption model is established to analyze the energy supply demand of electric vehicles under high-speed driving conditions.The influence of weather on traffic flow is analyzed,and the relationship between the electric vehicle charging load and weather is established based on the energy consumption model.The highway network model is established according to the geographic information system,the travel track of electric vehicles is simulated by using the traffic origin-destination analysis method,and the electric vehicle charging load in highway service areas is forecasted by combining the meteorological conditions along the highway.Taking an actual highway network as the example,the spatio-temporal distribution of the char-ging load in the service areas under various weather conditions is forecasted,and the influence of weather on the charging load in each service area is analyzed to verify the feasibility of the proposed method.
