This study addresses the quality of service (QoS) evaluation problem for electric vehicle (EV) fast charging stations (FCSs). With the increasing market penetration of EVs, effective service quality evaluation under different charging scenarios is a pressing and open issue for planning FCSs to accommodate non-stationary customer charging demand. Unlike previous studies, we make the first attempt to define the connotation of QoS from the EV customers' standpoint based on an extended universal generating function (EUGF). First, we formulate the charging behaviour as a fuzzy queuing process, where the arrival rate and service rate are modelled as fuzzy numbers. Second, the QoS requirement level is taken into account to better reflect the real charging environment. The model is then extended to incorporate the charging station structure by introducing the concept of the composition operator. Finally, numerical experiments are conducted to examine the performance of the EUGF-based model. The results demonstrate that the proposed approach is able to obtain a realistic and precise QoS evaluation, and can serve as an effective indicator for FCS planning and operation problems.
研究了电动汽车快速充电站的服务质量(QoS)评价问题。随着电动汽车市场渗透率的不断提高,在不同充电场景下进行有效的服务质量评估是规划fcs以满足非固定客户充电需求的一个紧迫而开放的问题。与以往的研究不同,本文首次尝试基于扩展通用生成函数(EUGF)从电动汽车用户的角度定义QoS的内涵。首先,我们将收费行为描述为一个模糊排队过程,其中到达率和服务率建模为模糊数。二是考虑了QoS要求水平,更好地反映了真实的收费环境。然后通过引入组合算子的概念,将模型扩展到充电站结构。最后,通过数值实验验证了该模型的性能。结果表明,该方法能够获得真实、精确的QoS评价,可作为FCS规划和运行问题的有效指标。
