光伏(PV)电解水制氢技术是实现PV消纳和绿电制氢的重要手段。在波动电源输入状态下,电解槽制氢系统运行稳定性及制氢经济性存在较多问题。针对这些问题,提出基于混合电解槽制氢系统的PV制氢方案,采用碱性电解槽(AEL)制氢系统与质子交换膜电解槽(PEMEL)系统相结合的方法,提出混合电解槽制氢系统功率优化控制技术和容量配置方法,在实现不同类型电解槽组合运行、合理配置的基础上,提升制氢性能。结果表明,与单一AEL制氢技术相比,混合电解制氢系统的制氢量提升了5%,波动率大幅降低,制氢成本相较于PEMEL电解水制氢系统大幅降低。采用功率优化控制技术后,同等功率运行下,制氢量提升。单一电解槽处于波动工况时,采用阵列轮换方式保证了电解槽系统安全运行。

Photovoltaic (PV) electrolytic water hydrogen production technology is an important way of realizing PV accommodation and green power hydrogen production. In fluctuating power input state, there are many problems in the operation stability of the electrolyzer hydrogen production system and the economy of hydrogen production. Aiming at these problems, a PV hydrogen production strategy based on hybrid-electrolyzer hydrogen production system is constructed, using the combination of alkaline electrolyer (AEL) water hydrogen production systems and proton exchange membrane electrolyzer (PEMEL) systems, and the power optimal control technology and capacity configuration method of the hybrid-electrolyzer hydrogen production system are proposed. Based on the combined operation and reasonable configuration of different types of electrolyzers, the performance of hydrogen production is improved. Results show that the quantity of hydrogen production of the hybrid electrolyzer hydrogen production system is improved by 5% compared with the single AEL hydrogen production system. The fluctuation rate and the hydrogen production cost are dramatically reduced compared with the PEMEL hydrogen electrolytic water production system. With the adoption of the power optimization control technology, the quantity of the hydrogen production is increased in the operation state with the same power. When the single electrolyzer is in the fluctuating working condition, the array rotation mode is adopted to ensure the safe operation of the electrolyzer system.
