摘　　要：针对大规模离网风电碱性制氢系统中电解槽的宽功率波动适应性及其使用损耗等问题,通过对比分析多台小容量电解槽组合与单台大容量电解槽对宽功率波动的适应能力,建立多台碱性电解槽共用一套气液处理装置(多对一)的离网风电制氢系统,并综合考虑碱性电解槽的效率特性和启停特性,以制氢系统利润最大为目标,提出一种基于鹈鹕优化算法(POA)的离网风电制氢多电解槽切换调度策略。对不同的切换调度策略进行仿真对比,结果表明,多对一离网风电制氢系统采用基于POA的切换调度策略能够更好地适应宽功率波动,同时减少电解槽启停次数,提高电解槽利用率。Aiming at the wide power fluctuation adaptability and service loss of electrolyzers in the large-scale off-grid wind power alkaline hydrogen production system,the adaptability of multi-small-capacity elec-trolyzer combination and single large-capacity electrolyzer to wide power fluctuation is compared and analy-zed,and then an off-grid wind power hydrogen production system with multiple alkaline electrolyzers sha-ring a set of gas-liquid treatment device(many-to-one)is established.Comprehensively considering the effi-ciency and start-stop characteristics of the alkaline electrolyzers,a switching scheduling strategy of multi-electrolyzer for large-scale off-grid wind power hydrogen production based on pelican optimization algorithm(POA)is proposed,with the goal of maximizing the profit of hydrogen production system.The simulation and comparison of different switching scheduling strategies show that,when the switching scheduling strategy based on POA is adopted,the many-to-one off-grid wind power hydrogen production system can better adapt to wide power fluctuation,reduce the start-stop times of electrolyzers and improve the utilization rate of electrolyzers.
