绿氢-绿氨工艺是指利用可再生能源发电、电解水制氢得到的氢气为原料合成氨的工艺流程，其具有受天气条件影响、负荷波动大、工段间耦合性强的特点。为研究绿氢-绿氨工艺流程中发输变电、电解水制氢、储氢、电化学储能、合成氨等工段之间的系统集成和协同调度方案，利用新一代流程模拟软件AVEVA Process Simulation建立了稳态-动态双模式通用型绿氢-绿氨全流程工艺模型，并通过多稳态模拟的手段分析了系统对天气变化的动态响应。结果表明，合理设计和调度储氢和储能单元不仅可以显著稳定化工生产、合理消纳可再生电力，还能稳定网电补充，提高整体经济效益。
Multi-steady state simulation and dynamics responses of green hydrogen-green ammonia production process
Ammonia synthesis based on hydrogen derived from renewable electricity(i.e.green hydrogen and green ammonia process)is frequently fluctuated due to weather change and the sections are highly coupled.To understand the synthesis and scheduling of power generation and transmission,hydrogen production by water electrolysis,hydrogen storage,electrochemical energy storage,and ammonia synthesis sections in green ammonia process,a generic process model for both steady-state and dynamics mode was developed using the next generation process simulation software,AVEVA Process Simulation,and the dynamics response of the model to weather fluctuation was investigated by means of multi-steady state simulation.The results show that optimized design and scheduling of the hydrogen storage and electricity storage modules can significantly stabilize the ammonia production,utilize excess renewable electricity,reduce grid power input,and thus,improve the economy.
