Abstract: With a scheduling time scale of 1 hour, based on the output characteristics and hydrogen production load characteristics of wind solar 8 760 hours, the coupling characteristics and economic benefits of wind solar hydrogen production under different grid electricity ratios were studied, in order to achieve the overall optimal economic benefits in the project scheduling process. The research results indicate that when the proportion of on grid electricity is within a certain range, the hydrogen production electricity consumption of the system remains basically unchanged, and the corresponding hydrogen production amount also remains unchanged. With the continuous increase in the proportion of grid connected electricity, there have been significant changes in hydrogen production and the proportion of abandoned electricity. In the integrated wind solar hydrogen production project, when the wind solar output cannot meet the power demand of the system’s non adjustable load, the system purchases electricity from the grid side, that is, the grid is only a supporting power source, so the proportion of electricity purchased is not affected by the proportion of grid connected electricity. The hydrogen production electricity price and hydrogen price will not have a minimum value at the same time. In the actual operation process of the integrated wind solar hydrogen production project, it is necessary to adjust the scheduling plan according to the project characteristics in order to obtain the lowest hydrogen price and achieve the overall optimal economic benefits of the project.
