Abstract

The inherent intermittent output characteristics of renewable energy sources (RES) have an adverse impact on the demand side, which greatly limits its penetration and utilization. In this context, emerging technologies for hydrogen production by water electrolysis provide the necessary flexibility to complement the uncontrollability of the power supply side for better integration of abundant RES. This paper mainly summarizes modelling, optimal scheduling, application scenarios and their assessment of large-scale water alkaline electrolyzers (WAE) in grid-connected operation modes, and discusses the challenges of WAE systems’ digitalization, optimal scheduling of green hydrogen, and future research directions of wind-hydrogen dominated renewable energy systems (WHDRES) based on artificial intelligence.
面向碳中和能源系统的大型并网碱性电解槽智能集成
可再生能源固有的间歇性输出特性对需求侧产生不利影响,极大地限制了可再生能源的渗透和利用。在此背景下,新兴的水电解制氢技术提供了必要的灵活性,以弥补供电侧的不可控性,更好地整合丰富的res。本文主要总结了大型水碱电解槽(WAE)在并网运行模式下的建模、优化调度、应用场景及其评估,并讨论了WAE系统数字化所面临的挑战。绿色氢的优化调度,以及基于人工智能的以风氢为主导的可再生能源系统(WHDRES)的未来研究方向。
