摘要(Abstract)：

固体氧化物电池可在燃料电池发电模式和电解制氢模式间切换，且工作温度为650～850℃，具有高品位余热回收利用的潜力,将固体氧化物电池用于热、电、氢联产可大幅提高设备利用率及能量利用效率。提出了光伏、光热驱动的固体氧化物电池热电氢联产系统，并耦合了蓄电池及熔盐蓄热保障系统连续稳定运行。以总成本最低为目标，构建系统容量配置及运行策略优化的混合整数线性规划模型，并基于品位对口、梯级利用的用能原则，采用夹点分析方法优化全系统多品位能流的梯级利用，揭示耦合系统物质和能量高效集成机理。针对某工业园区太阳能资源及热电氢需求实际案例，固体氧化物电池年满负荷运行小时数高于6 000 h，耦合系统平准化用能成本为0.28元/kW。
