摘要:

国内外对新型重力储能技术的开发较为广泛,但现阶段的重力储能应用方式容易受到自然条件及设备效率等问题的约束,难以建设大规模、大容量的储能电站。基于我国现有资源禀赋,提出一种固体流重力储能法,该方法可利用自然形成的大海拔高差,建设大规模的重力储能电站,保障高比例新能源新型电力系统稳定运行。介绍了固体流重力储能技术的工作原理、组成结构、核心技术、能量转换以及安全稳定性;对比几种主流重力储能技术的性能参数,并计算不同海拔下固体流重力储能技术的各项投资成本。通过对比阐明所提方法的工程研究意义以及该技术对生态环境改造的构思,尽管该技术仍处于初始阶段,但对于我国重力储能领域研究的推动具有重要意义。

Abstract:

The development of new gravity energy storage technologies is widespread both domestically and internationally. However, current applications of gravity energy storage are constrained by natural conditions and equipment efficiency, making it difficult to construct large-scale and high-capacity energy storage power stations. Based on China's existing resource endowments, a solid flow gravity energy storage method was proposed, which utilized naturally formed large altitude differences to construct large-scale gravity energy storage power stations, ensuring the stable operation of high-proportion new energy and new power systems. The working principle, composition structure, core technology, energy conversion, and safety and stability of solid flow gravity energy storage technology were explained. The performance parameters of several mainstream gravity energy storage technologies were compared, followed by an investment cost analysis of solid flow gravity energy storage technology under different altitude scenarios. The engineering research significance of the proposed method was clarified, along with its concept of ecological environment transformation. Although this technology is still in its initial stage, it is of great significance for promoting research in the field of gravity energy storage in China.
