摘要
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.关键词
