| In recent years,with the continuous growth of global energy demand,in order to achieve the goal of "carbon peaking and carbon neutrality",it is necessary to accelerate the transformation of traditional gasoline vehicles to new energy vehicles,and the development of new energy vehicles has been gradually promoted at the national strategic level.Among them,the surge in the number of electric vehicles poses a challenge to the competition of charging station operators;the random charging and discharging behavior of electric vehicles will also test the load balance of the power grid.For a long time,the research on charging and discharging behavior has focused on the homogeneity hypothesis,ignoring the influence of individual heterogeneity,and there are few studies on the vehicle owner’s discharging behavior preference.Therefore,in order to consider the individual heterogeneity of vehicle owners,this paper studies and analyzes the charging and discharging behavior of electric vehicles and guides and manages them.Firstly,two groups of experiments were conducted by using exploratory survey and SP(Stated preference)survey design,respectively investigating 90 and 88 electric vehicle driving subjects.By clarifying the nature of the survey and simulating experimental scenarios,the decision-making preferences of drivers in charging and discharging experiments were collected.Secondly,with the help of the binary logit model considering homogeneity,the multinomial logit model,and the latent category logit model considering heterogeneity,the charging experiment and the discharging experiment were analyzed respectively to explore the influence of vehicle owner heterogeneity on behavioral decision-making..The results show that in the charging experiment,electric vehicle drivers’ perceptions of queuing time and charging station familiarity show strong heterogeneity;the model considering individual heterogeneity divides the respondents into 60%and 60%of the respondents.40%of the two groups,including drivers with higher education and income levels and more adventurous drivers,have higher requirements for the quality of charging services,and the familiarity of charging stations has no significant effect on them.In the discharge experiment,a modeconsidering individual heterogeneity divides the respondents into two groups,75%and 25%,among which drivers with higher income levels and riskier attitudes have higher discharge to Low battery selection probability.This paper analyzes the research results of the two groups of experiments,and the research conclusions drawn to a certain extent make up for the shortcomings of this kind of scenario experimental research,and also try to provide corresponding reference opinions for power departments and charging station operators to speed up market research.points,guide car owners to use electricity,and make a modest contribution to the realization of my country’s energy-saving and emission-reduction goals. |
