The power supply and demand balancing system is a system in which power network companies use hydrogen power storage systems and pumped storage power generation to control the simultaneous equalization of power demand and supply.
When the supply of electricity across the entire power network exceeds demand due to factors such as good weather resulting in increased solar power generation, or strong winds resulting in increased wind power generation, the hydrogen power storage system will immediately increase demand to make up for the excess electricity, in accordance with instructions from the power supply and demand balancing system, using solid oxide electrolysis cells to produce hydrogen and consume electricity, and the pumped storage power plant will pump water from the lower dam to the upper dam and consume electricity.
In addition, when temperatures rise and demand for air conditioners and refrigerators increases, and the demand of the entire power network exceeds the supply, the hydrogen power storage system uses the hydrogen stored in the tank to generate electricity using a solid oxide fuel cell, and the pumped storage power plant uses water flowing from the upper dam to the lower dam to generate electricity, in response to instructions from the power supply and demand balancing system, in order to immediately increase the supply capacity for the excess electricity.
These will adjust the supply and demand of electricity throughout the electricity network.
By installing the hydrogen power storage systems so that their total output capacity exceeds the maximum power demand within the power network area by about 5%, it will be possible to supply electricity until the stored hydrogen runs out, even if all power sources such as solar and wind power are stopped.
This power reception adjustment system eliminates connection restrictions for solar and wind power generation and allows for expansion.
Hydrogen tank storage management
The amount of hydrogen stored in the hydrogen tanks of the hydrogen power storage systems at each location will be managed, and when it is likely to exceed the amount needed to adjust power supply and demand, hydrogen will be produced from the surplus electricity in the hydrogen power storage systems near airports and ports, and ammonia will be produced using the heat from the high-temperature heat storage device with that hydrogen and nitrogen in the air, and stored in the ammonia tank.This produced ammonia will be transported by tank truck to the airport or port and used for operating aircraft and ships.
Conversely, when the amount of hydrogen in the hydrogen power storage systems for the entire power network becomes extremely low compared to the amount needed to adjust power supply and demand, the ammonia stored in the ammonia tanks is converted into hydrogen and injected into the hydrogen tanks of the hydrogen power storage system to be used to adjust power supply and demand.
