摘要(Abstract):
针对未来大规模风光制氢问题,提出一种基于不同典型日下的风光制氢电解槽容量配置优化方法。首先对当地风光资源进行互补性分析,分析结果表明,当地风光资源互补性很好,有利于风光制氢的发展。然后分析每类典型日下的最优电解槽容量配置,并引入全年制氢相对最大收益衡量指标,从而得到了全局最优电解槽容量配置。最后分析了不同的影响因素对于绿氢制取成本的影响效果。结果表明,售氧和碳排放交易价格对绿氢成本有明显影响,并将其与传统制氢方式的成本进行了对比。当市场氧气价格为2000元/t时,风光制氢成本将对传统制氢成本产生初步竞争力;碳排放交易价格达到目前欧洲价格500元/t时,风光制氢成本已低于考虑碳捕集的煤制氢成本;当市场氧气价格达到2500元/t时,风光制氢成本将对传统技术制氢成本产生明显的竞争力。
Aiming at the problem of large-scale wind power and photovoltaic hydrogen production in the future, this paper proposes an optimization method for the capacity configuration of wind power and photovoltaic hydrogen production electrolytic cells based on different typical days. First of all, the complementarity of local wind and solar resources are analyzed. The analysis results show that the complementarity of local wind and solar resources is very good, which is conducive to the development of wind power photovoltaic hydrogen production. Then the optimal electrolytic cell capacity configuration of each type of typical day is researched, and the annual relative maximum revenue index of hydrogen production is introduced, thus the global optimal electrolytic cell capacity configuration is obtained. Finally, different influencing factors on the cost of green hydrogen production are analyzed. The results show that the cost of green hydrogen is significantly affected by the price of oxygen and carbon trading, and it is compared with the cost of traditional hydrogen production method. When the market oxygen price is 2000 yuan/t and the carbon trading price reaches the current European price of 500 yuan/t, the green hydrogen cost will have a preliminary competitiveness over the traditional hydrogen production cost. When the market oxygen price reaches 2500 yuan/t, the cost of green hydrogen will have obvious competitiveness over the cost of traditional hydrogen production.
