Case Study on Operation Mode of Photovoltaic Hydrogen Production and Hydrogenation Integrated Project

新能源发电制氢与电网的深度耦合、友好互补模式研究是氢能支撑新型储能及新型电力系统建设的关键环节。对光伏制氢加氢一体化项目氢气消纳市场、电力负荷特性、电力负荷预测和风光发电特性进行了分析,对“光伏发电灵活制氢,友好上网,谷电补充制氢”及“光伏发电优先制氢,余电上网,谷电补充制氢”两种运行模式进行了深入研究和分析。通过论证分析可知,“光伏发电灵活制氢,友好上网,谷电补充制氢”模式实现了“源-网-荷-储-用”上下游良好耦合与互补,以及本地电力及能源的综合高效利用,该模式比“光伏发电优先制氢,余电上网,谷电补充制氢”模式的供电净收入多196万元,经济效益更好。因此,推荐运行模式采用“光伏发电灵活制氢,友好上网,谷电补充制氢”模式。

The deep coupling and friendly complementary mode research between new energy generation hydrogen 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 generation,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 power 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 supplement 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".
