摘要提出一种采用熔融盐蓄热的非补燃压缩空气储能发电系统,通过将熔融盐储热与压缩空气储能相结合,实现电能的大规模存储和高效转换。利用熔融盐作为蓄热介质,将低谷电、弃风电、弃光电等电能转换为高品位热能存储,同时利用压缩机将空气压缩至高压,存储在储气装置中,发电时利用熔融盐储存的热能加热高压空气驱动涡轮机发电。完成了系统的流程设计,采用热力学基本原理分析了系统的运行特性,探索影响系统储能效率的关键因素,分析了涡轮机进口温度、涡轮机进口压力等参数对压缩机功耗、储气室容积、储能密度、储能效率等系统性能的影响。研究结果表明通过提高储热温度和涡轮机进口压力,可以显著提高系统的储能效率。该系统可以广泛消纳大规模的波动性电能,为大规模储能提供了一种新的技术途径。该研究结果可以为压缩空气储能以及新能源消纳提供参考。

Abstract：A non-supplementary fired compressed air energy storage (CAES) with molten salt thermal storage is proposed in this paper. Combined molten salt with compressed air energy storage, this system can achieve mass storage and efficient conversion of electrical energy. The off-peak power or abandoned wind and photoelectric power is converted into high-grade thermal energy, which is stored in the molten salt heat storage system. Meanwhile the air is compressed to high pressure and then stored in the gas storage device. The high pressure air heated by the molten salt can drive turbine to generate electricity when it is needed. The process design is completed with basic principle of thermodynamic analysis, and the key factors that affect the system efficiency are explored. The results show that the storage efficiency can be significantly improved by increasing the thermal storage temperature and turbine inlet pressure, which could provide a reference for compressed air energy storage as well as the renewable energy.

Key words： Compressed air energy storage molten salt heat storage peak load shaving efficiency of energy storage
