摘要：

Modeling of air-conditioning-building electrothermal coupling system is the basis of tapping the potential of air-conditioning (AC) regulation. In order to solve the problems of limited fitting accuracy and insufficient consideration of electrothermal coupling characteristics in the current research of second-order equivalent thermal parameter (ETP) modeling, the analytical recursive form of second-order ETP model is first derived. It has the advantages of high fitting accuracy, bounded recursive values and flexible and adjustable step size, which can improve the accuracy, reliability and adaptability of the model to diversified data acquisition technologies. Then, the average energy efficiency ratio is used to describe the electrothermal conversion process of AC, and the parameter identification method for the air-conditioning-building electrothermal coupling analytical model considering the average energy efficiency ratio is proposed. The indoor air temperature fitting mechanism and heating capacity fitting mechanism are comprehensively used to optimize the parameters. Finally, an actual test environment is built to verify the performance of the proposed method. The results show that this method can significantly improve the accuracy of parameter identification on the existing basis, so as to provide a more accurate and reliable model basis for the energy system simulation, AC load control and other applications. © 2023 Automation of Electric Power Systems Press.
