Salt rock cavern is recognized as an ideal medium for underground energy storage because of its integrity. With the proposal of Dual-carbon strategy, salt rock for underground renewable energy storage has attracted much attention. However, the high-frequency injection and production during the salt rock renewable energy storage operation have caused the high-frequency variation of the temperature and stress field in the salt cavern. In this paper, the thermal-mechanical coupling simulation of salt rock renewable energy storage has been conducted to acquire the long-term deformation characteristics under high-frequency injection and production, which is compared with the deformation of traditional salt rock energy storage. The results show that the maximum displacement of the surrounding rock increases by 7.8% when thermal coupling is considered in renewable energy storage. Compared with traditional energy storage, the thermal effect on renewable energy storage is more significant. The influence of the thermal effect should be concerned in the stability assessment of renewable energy storage.
