摘要
压缩空气储能(compressed air energy storage,CAES)是将电能转化为空气内能的一种储能方式,主要有传统压缩空气储能、先进绝热压缩空气储能(advanced adiabatic compressed air energy storage,AA-CAES)、超临界压缩空气储能和深冷液化空气储能(cryogenic liquid air energy storage,LAES)等技术类型,其中LAES具有储能密度高、储能容量大、寿命长、无污染、不依赖于地理条件且建设周期短等优点,是能量型储能发展趋势之一。首先对CAES的发展历程与趋势进行了阐述,针对LAES的技术特点,开展了其在电网中的应用分析和展望,明确了LAES的应用场景及效率,最后根据系统关键技术和难点,指出了该技术未来一段时间的后续研究重点。
Compressed air energy storage (CAES) is an energy storage method that converts electrical energy into air internal energy. It mainly includes traditional compressed air energy storage, advanced adiabatic compressed air energy storage (AA-CAES), supercritical compressed air energy storage, and cryogenic liquid air energy storage (LAES) etc. LAES technology has the advantages of high energy storage density, large energy storage capacity, long life, no pollution, independent of geographical conditions and short construction period. It is one of the development trends of energy storage. Firstly, the article elaborates the development process and trends of CAES. Based on the technical characteristics of LAES, its application in power grids is analyzed and forecasted, and the application scenarios and efficiency of LAES are clarified. Finally, According to the key technologies and difficulties of the system, it indicates the future research focus of the technology for a period of time in the future.
