The invention discloses a self-balancing underwater compressed air electric power energy storage system based on a flexible air storage device. The self-balancing underwater compressed air electric power energy storage system comprises the flexible air storage device, a compressor unit, an expansion generator unit, a heat accumulator and a floating platform, wherein the compressor unit is used forconverting electric energy into pressure energy of high-pressure compressed air and storing the high-pressure compressed air into the flexible air storage device, the expansion generator unit is usedfor releasing the pressure energy of the high-pressure compressed air from the flexible air storage device and converting the pressure energy into electric energy again, the flexible air storage device can store or release the pressure energy of the high-pressure compressed air and can control or adjust the buoyancy of the energy storage system, so that the floating platform can keep balance on the water surface. According to the self-balancing underwater compressed air electric power energy storage system, the technical economy of the underwater compressed air energy storage system can be remarkably improved, and therefore application and popularization of the underwater compressed air energy storage system in an offshore renewable energy power generation scene are promoted.

    本发明公开了一种基于柔性储气装置的自平衡水下压缩空气电力储能系统,包括柔性储气装置、压缩机组、膨胀发电机组、蓄热器和浮动平台;压缩机组用于将电能转化成高压压缩空气的压力能并能将高压压缩空气存储至柔性储气装置中,膨胀发电机组用于将高压压缩空气的压力能从柔性储气装置中释放并重新转化为电能,柔性储气装置能存储或释放高压压缩空气的压力能,且能控制或调节储能系统的浮力,使得浮动平台能够在水面保持平衡。本发明可以显著提高水下压缩空气储能系统的技术经济性,从而促进其在海上可再生能源发电场景中的推广应用。
