Aiming at the problem of economic capacity allocation of large-scale wind power hydrogen production under the goal of "double carbon" and improving the flexibility of power grid, this paper will analyze the scenario value of hydrogen energy storage participating in frequency modulation auxiliary service, and put forward the calculation method of economic capacity to realize the calculation of the optimal hydrogen production capacity of single wind farm and provincial wind power. Considering the scale cost effect of electrolyzed water hydrogen production system, taking the maximum net present value as the goal, and considering the power grid frequency regulation demand, the objective function of economic optimization of hydrogen production capacity is constructed, and the initial investment cost, hydrogen production electricity price, frequency modulation mileage, electrolytic cell conversion rate and equipment degradation rate of electrolyzed water hydrogen production system are sensitively analyzed, and on this basis, the future hydrogen production economy of wind farms/groups is predicted. Finally, a typical wind farm in Jilin Province is taken as an example for analysis. The results show that the participation of wind power hydrogen production in the frequency modulation auxiliary service market can maximize the consumption of wind power and improve the dynamic regulation capacity of the power grid, while achieving the optimal economic objectives.
