摘要
围绕风氢储系统中功率分配时未能充分考虑电解槽冷、热启动延时与储能系统协同运行的问题,提出考虑混合电解槽启停特性的系统精细化功率分配策略。首先,考虑碱性电解槽(AEL)和质子交换膜电解槽(PEMEL)运行特性,构建了混合电解槽数学模型,并进行分组轮换控制以实现混合电解槽阵列组内-组间功率合理分配;其次,引入构网型储能系统,在实现与电解槽启停和轮换阶段的动态耦合性的同时,保障了系统动态响应能力与制氢效率;然后,为确保系统功率精细化分配,提出基于模糊分段的功率分配算法模型,以改善系统的协调控制能力;最后,仿真结果表明,所提功率分配策略与采用简单时间均分策略下的单一PEMEL阵列和无轮换控制策略下的单一AEL阵列相比,可使混合电解槽各组的运行时间、启停次数更为均衡化,提升了制氢量,改善了系统的能量利用率。
Addressing the issue that power distribution in wind-hydrogen-storage systems often fails to fully account for the coordinated operation of electrolyzer cold/hot start delays and energy storage systems,a refined power distribution strategy is proposed for system considering the start-stop characteristics of hybrid electrolyzers.First,a mathematical model of hybrid electrolyzers is developed by considering the operation characteristics of alkaline electrolyzer(AEL)and proton exchange membrane electrolyzer(PEMEL),along with a grouping and rotation control strategy designed to achieve rational intra-group and inter-group power distribution within the hybrid electrolyzer array.Next,a grid-forming energy storage system is introduced,enabling dynamic coupling with the start-stop and rotation phases of the electrolyzers while ensuring system dynamic response capability and hydrogen production efficiency.Furthermore,to enable precise power allocation,a fuzzy segmentation-based power distribution algorithm model is proposed to enhance the system coordinated control capability.Finally,simulation results demonstrate that,compared with a single PEMEL array under a simple time-averaged allocation strategy and a single AEL array without rotation control,the proposed power allocation strategy balances the operation time and start-stop frequency of each hybrid electrolyzer group,increases hydrogen production,and improves system energy efficiency.
