中文摘要：

在分析典型冷热电联供（combinedcooling，heatandpower，CCHP）系统的基础上，提出描述其组成和结构的母线式结构，并围绕该系统结构设计了微网调度优化模型构架。在该结构中，选取电气、烟气、蒸汽、热水、空气作为基本母线，与源、负荷、储能和转换装置联接形成微网。使用该结构对各设备进行独立建模，有助于CCHP系统的灵活配置和通用建模。围绕该结构，建立联供型微网日前动态经济调度的O-1混合整数线性规划模型，最后通过测试算例证实了所提框架的合理性和有效性。

英文摘要：

On the basis of analyzing the components and structure of typical combined cooling, heat and power （CCHP） system, a newly bus-based structure was proposed for system description and a microgrid dispatch optimization model framework was designed according to it. Smoke, steam, water, air and electricity were selected as the five elemental buses in the proposed structure, integrating sources, load, energy storage and conversion devices into a microgrid. Furthermore, the structure was used for individual modeling of devices to capture flexible configuration and precise modeling. Utilizing this structure, a 0-1 mixed integer linear programming （MILP） model was established for CCHP microgrid＇s dynamic economic dispatch, the validity and effectiveness of which was verified on a test case.
