摘要:

空调负荷是最具潜力的需求侧资源之一。然而,由于建筑环境、用户偏好等因素的差异,空调负荷具有明显的异质性,脱离实际场景建立空调负荷异质性聚合模型,难以准确获取其聚合功率及响应潜力。在具体应用场景下,搭建了实际空调负荷集中控制系统,并在实际空调系统支持下,提出计及空调负荷二阶等效热参数模型参数时变特性的参数辨识方法。通过最小化二阶等效热参数模型仿真温度与实测温度误差,同时考虑参数的时变特性,建立优化模型,获得二阶等效热参数模型参数。算例结果表明,所提方法能够建立较为准确的空调负荷二阶等效热参数模型。

Abstract:

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.
