摘要
[目的]氢能是一种绿色高效的清洁能源,可以通过多种方式转化为电能、热能等加以利用。可再生能源制氢是实现碳达峰、碳中和目标的重要支撑。可再生能源制氢属于新型项目,是电力行业与化工行业的结合,系统间耦合性不强,提高能源综合利用率是可再生能源制氢的研究重点。[方法]文章介绍了当前主要的制氢工艺,对比了灰氢、蓝氢和绿氢的主要特点,阐述了风电及光伏制氢的主要系统,并提出了通过构建综合能源管理平台对可再生能源制氢各系统进行统筹管控的思路。[结果]在综合能源管理平台制定控制策略可以平衡功率,实现最优调度从而减少弃风弃光,而且还可以降低单位制氢成本。[结论]综合能源管理平台可以提高可再生能源制氢的能源综合利用率,对可再生能源制氢项目的推广起到支撑的作用,为可再生能源制氢领域的研究人员提供了重要的参考借鉴。
[Introduction]Hydrogen energy is a kind of green and efficient energy, which can be converted into electric energy and thermal energy by many ways. Hydrogen production from renewable energy is an important support to achieve the goal of "carbon peak and neutrality." Hydrogen production from renewable energy is a new kind of project, which is the combination of electric power industry and chemical industry. The coupling between systems is not strong. Improving the comprehensive utilization of energy is the research focus of hydrogen production from renewable energy. [Method]The main hydrogen production processes at present were introduced, the main characteristics of gray hydrogen, blue hydrogen and green hydrogen were compared, the main systems of hydrogen production from wind and photovoltaic power were described. Then it was proposed to build a comprehensive energy management platform to manage and control all systems of hydrogen production from renewable energy as a whole. [Result]The control strategy formulated on the comprehensive energy management platform can balance the power, optimize the scheduling, reduce the waste of wind and photovoltaic power, and reduce the unit hydrogen production cost. [Conclusion]The comprehensive energy management platform can improve the comprehensive utilization of hydrogen production from renewable energy, play a supporting role in the promotion of hydrogen production from renewable energy projects, and have important reference significance for researchers in this area.
