氢电混动汽车（fuel-cell hybrid electric vehicles，FCHEV）的出现有效促进了能源-交通系统的绿色低碳转型。现阶段关于FCHEV的研究主要集中在能量管理和控制策略上，较少关注灵活性潜力评估方面，为此，提出了一种计及车主充能意愿差异性的FCHEV集群灵活性潜力评估方法。首先，建立城市交通路网模型模拟FCHEV的出行特征，进而建立单体FCHEV充能模型；其次，利用改进层次分析法并结合熵权法建立车主充能意愿综合评价体系，并综合考虑禀赋效应和环保意识对车主响应意愿度的影响；最后，建立FCHEV集群灵活性潜力评估模型，求解得出潜力评估结果。仿真结果表明，所提方法在评估过程中能够合理刻画车主充能意愿的差异性，并有效提高集群参与优化调度时系统的灵活性。

The emergence of fuel-cell hybrid electric vehicles （FCHEV） has effectively promoted the green and low-carbon transformation of the energy-transportation system. At present, the research on FCHEV mainly focuses on energy management and control strategies, with little attention paid to the assessment of flexibility potential. Therefore, a FCHEV cluster flexibility potential assessment method that takes into account difference of owners′ willingness to charge is proposed. Firstly, an urban transportation network model is established to simulate the travel characteristics of FCHEV, and then a single FCHEV charging model is established; Secondly, the analytic hierarchy process is improved and combined with the entropy weight method to establish a comprehensive evaluation system for vehicle owners′ willingness to charge, and the impact of endowment effects and environmental awareness on electric vehicle owners′ willingness is comprehensively considered to respond. Finally, an FCHEV cluster flexibility potential assessment model is established and solved for the potential evaluation results. The simulation results show that the proposed method can reasonably characterize the differences in vehicle owners′ willingness to charge during the assessment process, and effectively improve the flexibility of the system when the cluster participates in optimization scheduling.
