摘要/Abstract

摘要： 压缩空气储能系统是一种大规模的能量存储技术，在可再生能源利用以及调峰领域发挥重要作用。储气室作为系统中主要的储能设备，其特性对系统运行有重要影响。为了研究储气室热力特性对AA-CAES系统性能的影响，设计能够提高系统性能的新型储气装置，建立实际、绝热、恒温3种储气室模型，并结合其他部件模型，对系统进行联合求解。分析求解结果发现，储气室绝热模型具有最高的储能效率，可以达到68.97%，恒温模型的储能密度最高，为2.4706 kW·h/m³，实际模型的储能效率和储能密度都较低；恒温模型下系统的性能受到环境温度的影响，提高环境温度可以使储能效率上升，但会导致储能密度下降；改进的储气装置能够结合绝热模型与恒温模型的优点，使系统性能获得改善。

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.

Key words: CAES, gas storage chamber, energy storage efficiency, energy storage density, optimization
