摘　　要：针对高温固体氧化物电解槽(SOEC)制氢能量转换效率、反应速率显著等特点,首先搭建多模绿氢集成运行模型,分析模型启停及制氢特性,并对其进行经济约束、运行约束。其次考虑风光的随机、间歇性因素及模块非线性特性,提出一种各模块独立受控和满足负荷要求的鲁棒可调协同优化方法。建立风光不确定集,将模块分段线性化,并引入鲁棒可调协同优化方法,以此来提高系统的产氢效率、运行灵活度和总经济效益。最后,在满足负荷分配工作的基础上对5个集成模块进行灵活启停运行算例分析,并将25个集成模块接入配电网参与到电网调度中。结果表明,在变负荷运行情况下,合理的组合模型不仅能优化系统启停运行的灵活性与稳定性,而且能提高新能源的消纳与并网友好性,具有明显的经济效益和战略意义。In view of the characteristics of high temperature solid oxide electrolyzer cell(SOEC)hydrogen production,such as energy conversion efficiency,remarkable reaction rate etc.,firstly a multi-mode green hydrogen integrated operation model is built to analyze the model’s start-stop and hydrogen production characteristics,while economic and operational constraints is imposed on it.Secondly,considering the random and intermittent factors of wind and solar power,as well as the nonlinear characteristics of modules,a robust and adjustable collaborative optimization method is proposed that independently controls each module and meets the load requirements.By establishing the wind and solar uncertainty set,the piecewise linearization of the modules,and introducing a robust and adjustable collaborative optimization method,the hydrogen production efficiency,operational flexibility,and overall economic benefits of the system were improved.Lastly,a flexible start-stop operation example analysis was conducted on 5 integrated modules on the basis of meeting the load distribution work,and 25 integrated modules were connected to the distribution network to participate in power grid scheduling.The results show that a reasonable combination model can not only optimize the flexibility and stability of the system’s start-stop operation under variable load operation conditions.Moreover,it can improve the consumption of new energy and the adaptability in grid-connection,which has obvious economic efficiency and strategic significance.
