In recent years, there has been a rapid change in the portfolio of road vehicles. This transformation needs to be supported by reshaping fuel stations. The existing structures can be modified to supply multiple vehicle types while utilizing renewable energies. In this article, we introduce a hybrid fuel station (HFS) to supply both electric and natural gas vehicles. We incorporate an energy hub and thoroughly explain the structure and components in detail. The configuration of the proposed HFS includes renewable energy sources (RESs), a power-to-gas unit (P2G), a natural gas distributed generator (NGDG), an energy storage device, a compressor, and a gas storage device. The optimal operation of the HFS will be under uncertainty due to multiple parameters that display unpredictable behaviors. Thus, a stochastic scheduling scheme considering features of the proposed HFS is presented. The resulted optimization is modeled as mixed-integer linear programming. The validity and capabilities of structure and scheduling schemes are evaluated with several numerical simulations. In particular, the impact of RESs, P2G, and NGDG on the operating cost of the HFS is analyzed. The results demonstrate that the economic benefits of the proposed HFS are significantly higher than a conventional one.

迈向基于小规模可再生能源中心的混合燃料站：评估结构和调度

近年来，道路车辆的产品组合发生了快速变化。这种转型需要通过改造加油站来支持。可以修改现有结构以在利用可再生能源的同时供应多种车辆类型。在本文中，我们介绍了一个混合燃料站 (HFS)，可为电动汽车和天然气汽车供电。我们整合了一个能源中心，并详细解释了结构和组件。提议的 HFS 的配置包括可再生能源 (RES)、电转气装置 (P2G)、天然气分布式发电机 (NGDG)、储能装置、压缩机和储气装置。由于多个参数显示出不可预测的行为，HFS 的最佳运行将处于不确定状态。因此，提出了一种考虑所提出的 HFS 特征的随机调度方案。结果优化被建模为混合整数线性规划。结构和调度方案的有效性和能力通过几个数值模拟进行评估。特别分析了 RES、P2G 和 NGDG 对 HFS 运营成本的影响。结果表明，所提出的 HFS 的经济效益显着高于传统的。
