摘　　要：能源和环境问题日益突出,可再生能源快速发展,其存在的间歇性是制约其发展的关键性问题之一。先进绝热压缩空气储能系统(AA-CAES)是解决可再生能源间歇性的有效方法。建立了AA-CAES储能阶段的数学模型并进行了能量守恒、平衡、各部件关键参数的动态分析和敏感性分析。结果表明,提出的数学模型遵循能量平衡和守恒定律;压缩机的损失大于换热器;能量和分别主要储存在导热油和高压空气中;压缩机运行工况与设计的偏差使储能阶段效率变低;空气流速和第一级透平入口温度对运行时间的影响大于储气温度、绝热效率和储气质量。本文研究为根据实际需求调节参数和优化储能系统提供参考。Energy and environment problems are becoming increasingly prominent,renewable energy is developing rapidly,and its intermittency is one of the key problems restricting its development.Advanced adiabatic compressed air energy storage(AA-CAES)is an effective method to address the intermittency of renewable energy.In this study,a mathematical model for the energy storage stage of AA-CAES is established,and dynamic and sensitivity analysis of the conservation of energy,energy balance,and key parameters of each component are conducted.The results reveal that the proposed mathematical model follows the laws of conservation of energy and exergy balance;the exergy loss of the compressor is greater than that of the heat exchanger;energy and heat are mainly stored in heat transfer oil and high-pressure air,respectively;the deviation between compressor operating and design condition reduces the efficiency;the effect of the air flow rate and inlet temperature of the first-stage turbine on the operation time is greater than that of the storage temperature,adiabatic efficiency and stored air mass.This paper provides reference for adjusting parameters and optimizing energy storage system according to actual demand.
