A study of the modeling technology of hydrogen production from renewable energy sources

The hydrogen energy storage technology based on the electric-hydrogen conversion mechanisms can realize wind and PV power consumption， smooth out wind and PV power fluctuations， and thus can be used as an important form of renewable energy power generation support. The construction of multivariate simulation models is an important means to promote the design and control of a wind-PV-hydrogen coupling system. The mechanistic models and common simplified models of wind power generation， photovoltaic power generation， and hydrogen production through electrolysis are introduced. The coupling characteristics of different renewable energy generation and hydrogen production are compared. Moreover， the application value of simulation models in operation and control optimization， source-grid-load interaction， and capacity configuration is illustrated based on domestic and foreign modeling cases. In view of the present technology development， the development of technology is analyzed and foreseen concerning the multi-physical field， multi-time scale， and multi-element to guide and facilitate the construction of related platforms and projects to accelerate the energy mix transformation towards zero-carbon energy supply and green energy use through the review of the basis for modeling of coupled hydrogen production from renewable energy sources.
