  • 摘要: 氢能具有巨大的发展潜力,被视为未来能源转型的重要组成部分。利用风光作为可再生能源技术与制氢相结合,为能源可持续发展提出解决方案。为优化碱性-质子交换膜混合电解槽多列运行调度,该文基于风光发电、氧中氢及多种电解槽模型,以系统净收益最大化为目标,提出了一种计及能耗特性的风光制氢碱性-质子交换膜混合电解槽多列优化策略,该系统离网式运行,可再生能源进行发电,配置蓄电池以确保系统稳定连续运行。结果表明:与传统同步运行且不考虑电解槽功率-效率特性的方案相比,使用碱性-PEM混合电解槽多列优化策略调度后,在不改变系统设备容量的前提下系统年收益提高12.47%,同时弃电率降低1.34%。该策略综合考虑两种电解槽之间动态响应差异,达到对风光资源的充分利用。最后,对系统电解槽容量配比进行了分析。研究成果有望为大型制氢项目碱性-PEM混合电解槽制氢生产调度提供一定的指导。

     

    Abstract: Hydrogen energy holds significant development potential and is crucial to the future energy landscape. Using wind power as a renewable energy technology combined with hydrogen production presents a solution for sustainable energy development. An optimization strategy is proposed in this study to optimize the scheduling of alkaline-proton exchange membrane (PEM) hybrid electrolyzers for multi-train operation, considering the differences in dynamic response and energy consumption characteristics based on wind power generation, hydrogen in oxygen and multiple electrolyzer models. The goal is to maximize net system revenue in an off-grid setup by harnessing renewable energy sources for power generation and incorporating storage batteries to ensure stable and continuous system operation. The results show that the multi-row optimization of the alkaline-PEM hybrid electrolyzers scheduling strategy increases annual revenue by 12.47% and reduces the power discard rate by 1.34% without altering the system equipment capacity, compared to conventional synchronous operation without considering the power-efficiency characteristics of the electrolyzers. This strategy accounts for the differences in dynamic response between the two types of electrolyzers, ensuring optimal utilization of wind and solar resources. Finally, the system electrolyzer capacity ratios were analyzed. The contribution of this study is expected to guide the scheduling of hydrogen production in alkaline-PEM hybrid electrolyzers for large-scale hydrogen production projects.
