Performance analysis and optimization of gas storage device in compressed air energy storage system
摘要
Abstract
Compressed air energy storage system is a large-scale energy storage technology, which plays an important role in the field of renewable energy utilization and peak regulation.As the main energy storage device in the system,the characteristics of the gas storage chamber have important influence on the operation of the system.In order to study the influence of thermal characteristics of gas storage chamber on the performance of AA-CAES system and design a new type of gas storage device which can improve the performance of the system,three kinds of gas storage models were established, which are practical, adiabatic and constant temperature model.And the mathematical model of the system was solved combined with other parts of the system.Analytical results showed that the adiabatic model of gas storage chamber had the highest energy storage efficiency which could reach 68.97%.The energy storage density of the constant temperature model was the highest,which is 2.4706kW·h/m.And the performance of the actual model were poor.The performance of the system under the constant temperature model was affected by the environment temperature.The energy storage efficiency could be increased with the increase of the environment temperature, but the storage density could be decreased.The improved gas storage device could combine the advantages of the adiabatic model and the constant temperature model which could improve the performance of the system.关键词
