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.
