摘要

阵列式换热器作为换热器网络（heat exchanger network，HEN）的一种拓展，能够有效提升先进绝热压缩空气储能（advanced adiabatic compressed air energy storage，AA-CAES）发电系统的运行能力。然而变结构阵列式换热器网络的复杂性会对 AA-CAES运行能力产生显著影响。为此，本文提出了一种计及阵列式换热器的先进绝热压缩空气储能系统宽工况运行方法。首先基于热电比拟理论建立了 AA-CAES系统用阵列式换热器模型。随后，基于阵列式换热器的运行特点提出了一种 AA-CAES宽工况运行方法，根据需求功率确定参与功率调节的换热器单元数量后以功率偏差、导热油余能作为目标函数对阵列式换热器进行多目标优化。最后基于一商业运行压缩空气储能电站参数进行算例分析，验证了所提方法的有效性。结果显示相较传统换热器，阵列式换热器能够有效拓宽 AA-CAES发电系统运行可行域，减少功率跟踪偏差并增加导热油能量利用率。该研究将为压缩空气储能电站的灵活调控提供理论依据和技术支撑。

Abstract

As an extension of the heat exchanger network （HEN）， the array-type heat exchangers can effectively enhance the operational capability of Advanced Adiabatic Compressed Air Energy Storage （AA-CAES）. However，the complexity of the variable-configuration array-type heat exchanger network exerts a significant influence on the operational capability of the AA-CAES system. To address this gap， this paper proposes a wide-range operational strategy for AA-CAES systems that incorporates array-type heat exchangers. First， a model of the array-type heat exchangers array for AA-CAES is established based on the thermal-electrical analogy theory. Subsequently， a widerange operation method for AA-CAES is proposed， leveraging the operational characteristics of the array-type heat exchangers. This method determines the number of heat exchanger units participating in power regulation according to the required power output， followed by a multi-objective optimization of the array-type heat exchangers using power deviation and residual thermal energy of the thermal oil as objective functions. Finally， a case study based on the parameters of a commercially operational AA-CAES station is conducted to validate the effectiveness of the proposed method. The results demonstrate that， compared to traditional heat exchangers， the modular heat exchanger array can effectively expand the feasible operating region of the AA-CAES discharging system， reduce power tracking deviation，and increase the utilization rate of thermal energy in the thermal oil. The research will provide the theoretical foundation and technical support for flexible regulation of AA-CAES.
