[0002] By the end of 2023, the national hydrogen production capacity will exceed 49 million tons / year, an increase of about 2.3% year-on-year; the output will exceed 35 million tons, an increase of about 2.3% year-on-year, mainly used as intermediate raw materials for industrial processes such as synthetic ammonia, methanol, and refining. The production capacity of hydrogen produced by water electrolysis is about 45 tons / year, an increase of about 10.5% year-on-year; the output is about 30 tons / year, an increase of about 5.1% year-on-year. New energy power generation systems such as wind and solar have the characteristics of instability and periodicity. The power grid has restrictions on the access to the grid for new energy power generation. With the continuous iteration and update of water electrolysis hydrogen production technology and the continuous expansion of hydrogen consumption, water electrolysis hydrogen production stations have developed rapidly.

[0003] In the prior art, when users use hydrogen products or services, there are blocked channels or delays in transmitting demand information at the hydrogen-using end.

This can avoid the waste of resources and increased storage costs caused by overproduction of hydrogen, and also prevent insufficient hydrogen supply from affecting the normal production and use of downstream users. Sending the data of electrolysis equipment that is normally started and cannot be started at the hydrogen production station to the control system of the hydrogen production station can allow the control system to better understand the status of the equipment, thereby optimizing the utilization of the equipment. The hydrogen production scheduling instructions generated by the embodiment of the present invention based on accurate equipment status data and supply and demand conditions can make the production scheduling of the hydrogen production station more scientific and reasonable. The control system can accurately control the hydrogen production according to the scheduling instructions, thereby improving the flexibility and response speed of production.

[0093] When the total hydrogen demand of users is greater than the maximum hydrogen production of the hydrogen production station, the green electricity hydrogen production intelligent dispatching system will issue an alarm message and feed back to the downstream hydrogen users respectively. When the user's demand cannot be met in time, based on the convenient feedback channel, the user can understand the actual hydrogen supply situation and adjust the demand in time, thereby improving the user experience.
