Research on the Comprehensive Benefit Evaluation of Electric Vehicle Technology Promotion and Application Under the Strategic Background of “Carbon Peaking and Carbon Neutrality”

다국어 초록 (Multilingual Abstract)

On the one hand, as a substitute for traditional fuel vehicles, electric vehicles (EV) is an important measure to achieve “carbon peak and carbon neutralization” in transportation. On the other hand, as an energy storage unit in the new power system, it can make up for the disadvantages brought by renewable energy power generation. Therefore, scientifc and efective evaluation of EV benefts is the premise to promote the development of EV. In view of the characteristics of EV involving many interest groups and huge market potential, this paper introduces the comprehensive evaluation theory in operations research: analytic hierarchy process (AHP) and entropy weight method, and combines the respective advantages of the two methods to avoid the distortion of evaluation results caused by a single evaluation method. First of all, under the background of building a new power system and realizing a powerful automobile country, the EV promotion beneft evaluation index system is constructed from fve frst-class indexes and 18 s-class indexes of consumers, distribution network, charging network, social beneft and environmental beneft. Then, aiming at the shortcomings of single evaluation method, the subjective and objective combination method of AHP entropy weight method is established to solve each weight index, so as to realize the scientifc quantifcation of the index. Finally, a certain area of a coastal city is selected for example analysis. The results show that the evaluation method established in this paper has a positive efect on EV promotion, and can provide suggestions for EV promotion.
