摘要
随着可再生能源的快速发展,为应对间歇性和可变电力生产带来的挑战,电网侧能源存储解决方案的需求不断增加.卡诺电池作为多种成熟电热转换和存储技术的集成,因其可扩展性和不受地理限制的优势,正受到越来越多的关注.综述卡诺电池的基本原理、关键技术、应用前景及当前研究现状;探讨了高温卡诺电池技术的定义,以及关键设备如压缩机和膨胀机的运行特性与技术挑战;分析了基于电加热和双向循环(如布雷顿循环和朗肯循环)的卡诺电池系统的实际应用案例和技术前景,为未来研究和技术开发提供参考.
Abstract
With the rapid development of renewable energy,the demand for grid-scale energy storage solutions is increasing to address the challenges posed by intermittent and variable power generation.As an integration of various mature electrothermal conversion and storage technologies,Carnot battery is gaining increasing attentions due to its scalability and independence from geographical constraints.The fundamental principles,key technologies,application prospects and current research status of Carnot battery are reviewed.The definition of high-temperature Carnot battery technology and the operational characteristics and technical challenges of related key equipment such as compressors and expanders are discussed.Additionally,practical application cases and technological prospects of Carnot battery systems based on electric heating and bidirectional cycles(such as Brayton and Rankine cycles)are analyzed,providing a reference for future research and technological development.
