摘要
[目的]压缩空气储能(Compressed Air Energy Storage,CAES)是1种可大规模储存电力能源的技术,其规模仅次于抽水蓄能,储气装置是其重要的组成部分。国内外已投入商业运行的压气储能电站的储气装置多为盐穴、废弃矿坑等天然地质构造,大规模长时压缩空气储能有赖于更具经济性及广泛适用性的储气装置。[方法]人工地下洞室储气库较大程度上摆脱了压缩空气储能电站对于特殊地质条件的依赖,成为大规模建设长时压气储能电站的有力支撑,但国内外相关研究成果较少,摸清国内外研究现状,总结其他行业先进经验,理清该领域亟待突破的难题,对于大规模建设压气储能电站具有重要意义。[结果]压气储能电站地下人工洞室与天然气储气库及水电输水隧洞等常规人工洞室运行特点有较大不同,目前对于该领域尚缺乏成熟的设计方法与规程规范,有诸多关键技术仍有待解决,文章对压气储能电站地下人工洞室的特点及重点研究内容进行了梳理。[结论]创新是自主建设压缩空气储能电站地下硬岩储气库的唯一出路,在安全的大前提下兼顾经济性并突破,该技术对丰富我国储能发电技术,完善新型电力系统具有重大的现实意义,若该技术发展成熟,可为我国新型电力系统的构建提供强大的保障。
[Introduction]Compressed air energy storage(CAES)is a technology for storing electrical energy on a large scale,only second to pumped storage in terms of scale.The gas storage device is an important component of CAES.The gas storage facilities of compressed air energy storage power plants that have been put into commercial operation domestically and abroad are mostly natural geological structures such as salt caverns and abandoned mines.Large-scale,long-term compressed air energy storage requires more economical and widely applicable gas storage facilities.[Method]Artificial underground cavern gas storage facilities largely freed compressed air energy storage power plants from the reliance on specific geological conditions,becoming a strong support for the large-scale construction of long-term compressed air energy storage power plants.However,there were few research achievements in this field domestically and internationally.Understanding the research status at home and abroad,summarizing advanced experiences from other industries,and clarifying the challenges that need to be addressed urgently in this field had significant implications for the large-scale construction of compressed air energy storage power plants.[Result]There are significant differences in the operating characteristics between artificial underground caverns in compressed air energy storage power plants and conventional artificial caverns such as natural gas storage facilities and hydroelectric water conveyance tunnels,and there is a lack of mature design methods and regulations for this underground artificial caverns in compressed air energy storage power plants.[Conclusion]Prioritizing safety,considering cost-effectiveness and fostering innovation provide a guarantee for the independent development of the underground hard rock gas storage facilities for compressed air energy storage power plants.This technology holds practical significance in enriching China's energy storage and power generation experiences,and improving new power systems.If this technology matures,it can provide strong support for the construction of a new power system in China.
