【 摘 要 】
Compressed air energy storage system is developing rapidly as the most promising energy storage technology, and gas storage device is one of the main components of compressed air energy storage system. Aquifer compressed air energy storage can break the dependence of traditional compressed air energy storage on geological conditions such as large rock caves, and can realize large scale storage of compressed air. In this paper, the development and progress of compressed air energy storage in aquifer are summarized firstly. Then, taking 3.5 Mw energy storage scale as an example, the energy storage model of underground aquifer with buried depth of 800m in horizontal stratum is established by using numerical simulation method. The formation of the initial airbag after gas injection and the cycle times of the pressure system during the system cycle are analyzed. The experimental results show that after a complete cycle, the pressure change in the formation is small as the cycle continues, the effective gas phase volume in the formation for the energy storage release cycle is slowly reduced.The aquifer has wide distribution and good sealing. It is feasible to store compressed air as a gas storage. The corresponding system design should be carried out according to the actual geological conditions.【 预 览 】
