摘要
将可再生能源发电制氢集成于炼厂氢气系统中,不仅可替代部分氢气公用工程以满足炼厂的氢气需求,同时也可为炼厂中旋转设备提供电能,但可再生能源发电制氢的波动性将影响氢气网络的稳定运行。为了探究风力发电制氢与氢气网络集成中两个子系统平抑风能波动的特性,本文构建了集成风力发电制氢的氢气网络数学优化分析模型,研究了氢气网络平抑风力发电制氢波动的经济性和系统结构特性。研究表明,为了适应可再生能源发电制氢的波动,氢气网络需要更加复杂的网络结构,且风力发电制氢输出的电力和氢气经储能电池和氢气储罐的缓冲调节后仍存在较大波动,氢气网络仍需通过调节公用工程和燃气系统来实现氢气网络的稳定运行。
Integrating renewable energy system into a hydrogen network can replace a part of hydrogen utility to meet the hydrogen demand in a refinery.Meanwhile,it also provides electricity for the rotating equipment in the refinery.However,the fluctuation of hydrogen will affect the stable operation of the hydrogen network.To explore the characteristics of the two subsystems in suppressing fluctuations of wind power generation,a mathematical programming model for the hydrogen network integrated with wind power to hydrogen system is established to investigate the economy and structure characteristics of the hydrogen network for suppressing the fluctuations of the hydrogen stream from wind power generation.The results show that,to accommodate fluctuations,a more complex structure of the hydrogen network is required.The power and hydrogen outputs from the wind power generation system still fluctuate greatly after the batteries and hydrogen storage tanks buffering.It is critical to adjust the flowrate of hydrogen utility and fuel gas system to achieve stable operation of the hydrogen network.
