蓄热式重力压缩储能装置及发电系统研究
摘要
Abstract
With the rapid development of renewable energy,the demand for various types of energy storage technologies in the power grid continues to grow.Gravity energy storage is environmentally friendly and economical,and has received widespread attention in the power field in recent years.In this paper,a gravity compressed air energy storage device and power generation system based on a regenerative gravity block are designed.The energy storage device includes a shaft,a gravity column,a piston,etc.,and the power generation system includes a vertical elevator and a generator.By dividing the gravity plunger into multiple gravity columns arranged layer by layer,the gravity columns are limited through a limit mechanism,and the gravity acting on the gas storage chamber is changed to achieve pressure adjustment.There is no need to adjust the adjusting valve of the air expansion unit to adjust the incoming gas flow and pressure,achieving energy-saving effect.At the same time,the compressed gas and the gas introduced into the air expansion unit during the expansion process pass through the heat storage material,and heat exchange during the compression and expansion processes is realized through the heat storage material.There is no need to arrange additional heat exchange units,which improves the flexibility of system design and has practical value.关键词
