摘要综合能源系统(integrated energy system, IES)是未来能源利用方式的重要发展方向，实现多区域IES的协同规划与调度对进一步提高其经济效益和环境效益至关重要，为此首要的问题是区域冷、热网(district heating and cooling networks, DHC)的建模。本文基于传热学的基本原理建立了区域热网能量传输通用模型。推导出热网能量流基本方程，对其线性化得到热网能量流模型，同时推导了用于求解热网潮流（热媒流量、温度）的网络流量-温度基本方程。在冷热电联供(combined cooling, heating and power, CCHP)系统调度模型基础上建立了含有热网的多区域IES优化调度混合整数线性规划模型。通过算例比较了独立IES和多区域IES经济运行，简要分析了两种情境下的系统工况与经济性能，同时验证了热网模型的有效性。87478

Title    Research on the integrated energy system considering  the character of heat network                         

Abstract Integrated energy system (IES) is an important developing direction for future energy use。 It is vital for further improving the economic and environmental benefit to realize collaborative planning and dispatching of multi areas IES, where the first problem is modeling of district heating and cooling network (DHC)。 A general model for energy transfer of district heating network was established based on the heat transfer theory。 The energy flow function for the heating network was derived, and then was linearized to form the energy flow model of heating network。 For solving heating network’s flow and temperature, the flow-temperature function was derived。 Based on the combined cooling, heating and power (CCHP) system dispatching model, a mixed integer linear programming model (MILP) for optimal dispatching of multi-IESs with heating network was established。 Working condition and economic performance of the System was briefly analyzed based on the case study, and validity of the model was verified。
