Case Study on Operation Mode of Photovoltaic Hydrogen Production and Hydrogenation Integrated Project
The deep coupling and friendly complementary mode research between new energy generation hy-drogen production and the power grid is a key link in hydrogen energy support for new energy storage and the construction of new power systems.An analysis is conducted on the hydrogen consumption market,power load characteristics,power load forecasting,and wind solar power generation characteristics of the photovoltaic hydrogen production and hydrogenation integration project.Two operating modes,"flexible hydrogen production through photovoltaic power generation,friendly grid connection,and valley power supplement hydrogen production" and "priority hydrogen production through photovoltaic power genera-tion,grid connection of surplus electricity,and valley power supplement hydrogen production",are deeply studied and analyzed.Through argumentation and analysis,it can be concluded that the "photovoltaic pow-er generation flexible hydrogen production,friendly grid connection,and valley power supplement hydrogen production" model achieves good coupling and complementarity between the upstream and downstream of "source grid load storage utilization",as well as comprehensive and efficient utilization of local electricity and energy.This model has a net power supply income of 1.96 million yuan higher than the "photovoltaic power generation priority hydrogen production,surplus power grid connection,and valley power supple-ment hydrogen production" model,with better economic benefits.Therefore,it is recommended to adopt the operation mode of "flexible hydrogen production through photovoltaic power generation,friendly grid connection,and supplementary hydrogen production through valley power".
