摘　　要：随着可再生能源的大规模并网,电力系统调节手段不足的问题越来越突出,原有的辅助服务模式和力度已不能满足系统运行需求。而质子交换膜(proton exchange membrane,PEM)电制氢具备适应高比例、大规模可再生能源并网的快速功率跟踪调节能力,为调峰合理分配电能提供了一种新策略。因此,该文以PEM电解槽为核心构造并网风光互补制氢系统。为全面评估PEM电制氢的调峰能力,在全时制氢、重点填谷的方式下提出调峰多功率模式控制策略。同时,兼顾调峰经济性、技术性和灵活性指标,构造多目标优化调峰能力评估模型。基于改进的NSGA-Ⅲ(non-dominated sorting genetic algorithmⅢ)算法对算例进行优化求解,得到不同调度场景下的调峰能力指标,并验证了所提策略及模型的有效性。结果表明,PEM电制氢在最大化消纳可再生能源、提高系统下调灵活性的同时,有望通过降本增效来提升可再生能源制氢的市场竞争力,并实现其规模化应用。With the large-scale grid connection of renewable energy,the problem of insufficient regulation means of the power system is becoming increasingly prominent,and the original auxiliary service mode and strength can no longer meet the system operation demand.The PEM electro-hydrogen production can adapt to the high proportion and large-scale renewable energy grid-connected fast power tracking and regulation,which provides a new strategy for the reasonable distribution of power for peaking.Therefore,this paper constructs a grid-connected wind-solar hybrid hydrogen generation system with a PEM electrolyzer as the core.To comprehensively evaluate the peak shifting capability of PEM hydrogen production,a peak shifting multi-power mode control strategy is proposed under the approach of full-time hydrogen production and focused valley filling.At the same time,a multi-objective optimization peak shifting capacity assessment model is constructed considering the peak shifting economy,technology,and flexibility indexes.Based on the improved NSGA-III algorithm,the algorithm is optimized and solved to obtain the peaking capacity indicators under different scheduling scenarios,and the effectiveness of the proposed strategy and model is verified.The results show that while maximizing the consumption of renewable energy and improving the flexibility of system down-regulation,PEM hydrogen production is expected to enhance the market competitiveness of renewable hydrogen production through cost reduction and efficiency enhancement and to realize its large-scale application.
