Abstract: In the previous dispatch model,the response delay characteristics of the hydrogen-electric link hydrogen fuel cell（HFC） as a power source in the hydrogen energy storage system were ignored,which would cause load shedding of the power grid and affect its stable operation. The optimal operating temperature of HFC is different under different loads. When HFC starts at room temperature,the change of operating temperature is the main factor that causes its response delay. Therefore,aiming at the working temperature of HFC,this paper analyzes the response delay characteristics of HFC,establishes its response delay characteristic model,and analyzes the influence of load on its response time,and obtains its response time under different load rates. Finally,combined with the characteristics of the intraday dispatch period of the power grid,the intraday dispatch strategies that is formulated can respond to different dispatch periods according to the different load rates of the HFC.
