摘　　要：针对调频资源不足导致的电网频率稳定性下降问题,以电解水制氢系统为研究对象,通过精细化建模并提出针对性控制策略,使电解水制氢系统提供快速频率响应,充分发挥电解水制氢系统内电、氢、热能的调频潜力,并对电解水制氢系统提供快速频率响应的机理及效果进行仿真验证。结果表明:所建立的模型可揭示电解水制氢系统的电-氢-热耦合机理,表征电解水制氢系统的频率响应特性;在多类扰动场景下,电解水制氢系统提供快速频率响应均可增强电网的频率稳定性。In view of the decline of frequency stability in the power grid caused by the shortage of frequency regulation resource,this paper takes electrolytic water hydrogen production system as the research object,through establishing a refined dynamic model and the targeted control strategy,so that electrolytic water hydrogen production system can provide fast frequency response,which fully exploits the frequency regulation potential of electrical,hydrogen and heat energy within the electrolyzers system.In addition,the mechanism and ability of the fast frequency response provided by the electrolyzers are analyzed.The results show that the established model can reveal the electric-hydrogen-thermal coupling mechanism and characterize the frequency response characteristics of the electrolyzers system during the fast frequency response.The fast frequency response provided by the electrolyzers system can improve the frequency stability of the power grid under multiple disturbance scenarios.
