In response to the instability problem of distributed new energy as an independent power source supplying energy to household energy systems

a capacity configuration method for distributed home energy systems based on hydrogen energy is proposed. This method is based on the characteristics of hydrogen energy that can suppress wind and solar fluctuations and flexibly convert load demands

and constructs a hydrogen coupled distributed energy family terminal energy system structure. Combining with the characteristics of renewable resources in the region

a hydrogen based distributed household energy system capacity allocation model is established with the goal of minimizing the net total cost. Taking the wind and solar resources and typical household energy data in Xinjiang region as an example

the impact of the configuration capacity of distributed energy and hydrogen energy systems on the system is simulated and analyzed

and the optimal capacity configuration of hydrogen energy systems under the optimal wind and solar ratio conditions is obtained. From the simulation results

it can be seen that the proposed model can effectively reduce the total cost of the household energy system while achieving reliable energy supply off the grid

and promote the consumption of new energy

which provides suggestions for the design of distributed household energy based on hydrogen energy.
