Abstract

The invention discloses a suspension type gravity energy storage system and method. The system comprises an electric device, a power generation device, a transmission device, a gravity block, a gravity pool, a compressed air source, an air storage device and an air compression device. The gravity block is connected with the electric device and the power generation device through the transmission device, the lower side of the gravity block is located in the gravity pool, the buffer device and the pressure relief device are arranged at the bottom of the gravity pool, the gravity pool is communicated with the compressed air source, the air storage device and the air compression device, and the air storage device is communicated with the compressed air source. The system and the method have the characteristics of high safety, stable landing and no energy consumption.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and relates to a suspended gravity energy storage system and method. Background technique [0002] The energy storage technology coupled with new energy power generation technology and peak-shaving and frequency-regulating technology has developed rapidly in recent years. The main schools of energy storage technology are divided into electrochemical energy storage, pumped storage, compressed air energy storage, thermal energy storage, and gravity storage. energy, flywheel energy storage, etc. Gravity energy storage has the advantages of high energy storage efficiency, high stability, and fast response speed. At the same time, it has disadvantages such as low energy density and large footprint. At present, there are few commercial applications. India is building a 35MW gravity energy storage system, and Scotland will also Build a 250kW gravity energy storage system. [0003] The mass of m...
