由于综合能源系统中的设备元件构成复杂，涉及电、气、热、冷多种能源形式的设备元件在互联和传送过程中产生了海量、异构的数据，无法较好的反映综合能源系统特性。 鉴于此，本文以综合能源系统基础单元为研究基础，基于统计聚类法分析精选出综合能源系统典型基础单元设备，提取综合能源系统典型基础单元设备特征数据表征基础单元特性，根据综合能源系统基础单元的能质属性，建立综合能源系统各类基础单元模型，更全面地表征综合能源系统特性。通过算例分析，验证了所提各类综合能源系统基础单元模型的合理性和适用性。

Due to the complexity of equipment components in integrated energy systems, which involve multiple forms of energy such as electricity, gas, heat, and cooling, a vast and heterogeneous amount of data is generated during interconnection and transmission processes, making it difficult to effectively reflect the characteristics of integrated energy systems. In light of this, this paper adopts integrated energy system basic units as the research foundation. Based on statistical clustering analysis, typical basic unit devices of integrated energy systems are carefully selected. Characteristic data of these typical basic unit devices are extracted to represent the characteristics of basic unit in integrated energy systems. Various models of basic unit in integrated energy systems are established based on the energy and quality attributes of these basic unit. Through case studies, the rationality and applicability of the proposed models for various types of basic unit in integrated energy systems are validated.
