采用基于混合整数线性规划的最优运行规划模型，分析了采用无反向功率流日启停运行的住宅用聚合物电解质燃料电池热电联产系统（PEFC-CGS）与插电式混合动力汽车（PHEV）联合运行的节能效果。这种组合使用的目的是通过在深夜使用PEFC-CGS输出为PHEV充电来增加PEFC-CGS的电容系数，并针对不允许从住宅热电联供系统到商业电力系统的反向电力流动的地区的应用，例如日本。首先，开发了PEFC-CGS的最优运营规划模型，该模型包含了PEFC-CGS的日常启停操作。PEFC-CGS和PHEV的组合使用的节能效果，然后分析的基础上观察的最佳操作模式为0.75 kWe PEFC-CGS，模拟的能源需求与采样时间为5分钟，和各种每日运行距离的PHEV。结果表明，与单独使用PEFC-CGS、PHEV单独使用相比，PEFC-CGS与PHEV的联合使用提高了PEFC-CGS的电容率和热水供给率，节约了能源。因此，该可行性研究表明，PEFC-CGS和PHEV的组合使用为住宅和交通部门的节能提供了协同效应。
The energy-saving effect of a residential polymer electrolyte fuel cell cogeneration system (PEFC-CGS) that adopts a daily start–stop operation with no reverse power flow, combined with a plug-in hybrid electric vehicle (PHEV) is analyzed by optimal operational planning model based on mixed-integer linear programming. This combined use aims to increase the electric capacity factor of the PEFC-CGS by charging the PHEV using the PEFC-CGS output late at night, and targets the application in regions where the reverse power flow from residential cogeneration systems to commercial electric power systems is not permitted, like in Japan. First, the optimal operational planning model that incorporates the daily start–stop operation of the PEFC-CGS is developed. The energy-saving effect of the combined use of the PEFC-CGS and PHEV is then analyzed on the basis of observations of the optimal operation patterns for a 0.75-kWe PEFC-CGS, a simulated energy demand with a sampling time of 5 min, and various daily running distances of the PHEV. The results show that the combined use of the PEFC-CGS and PHEV increases the electric capacity factor and hot water supply rate of the PEFC-CGS and saves more energy in comparison with their separate use in which the PEFC-CGS is used but the PHEV is charged only using purchased electric power. Consequently, this feasibility study reveals that the combined use of the PEFC-CGS and PHEV provides the synergistic effect on energy savings in the residential and transport sectors.
