Air conditioning load (ACL) is one of the most potential demand response (DR) resources. However, due to the diversity of the building environment and the users’ preference, heterogeneity is a key characteristic of ACL. Modeling without considering real application is negative for deriving the aggregate power and actual potential of ACL. A real centralized ACL control system is developed based on real applications. With the support of the hardware system, parameter identification method considering time-varying characteristic of the second-order equivalent thermal parameter (ETP) model is proposed for ACL. The parameters of the second-order ETP model is derived by minimizing the error between the simulated temperature and actual temperature, and at the same time considering the time-varying characteristic of the parameters. The results show that the proposed method can derive accurate second order ETP model for ACL.
