Coordination efficiency between different energy sectors with privacy preservation has become a technical bottleneck in distributed operation of the integrated electricity and heat systems (IEHS). This article investigates, for the first time, an equivalent model-based non-iterative solution for this issue. An equivalent model of district heating networks (DHNs) retaining the temperature quasi-dynamics is derived. Based on the equivalence, all the state variables in DHNs are explicitly expressed by the heat power generation, and the feasible region of DHNs is projected on the coupling boundaries of the IEHS. The existence of this equivalent model is proved under a mild sufficient condition. The application of the proposed equivalent model is demonstrated via the distributed unit commitment for IEHS. Case studies of two test systems validate the effectiveness and the efficiency of the solution for distributed IEHS operation.

区域供热网络的动态等效模型：公式，存在性及在分布式电热运行中的应用

具有隐私保护功能的不同能源部门之间的协调效率已成为集成电热系统（IEHS）分布式运行中的技术瓶颈。本文首次研究了此问题的等效的基于模型的非迭代解决方案。推导了保留温度准动力学的区域供热网络（DHN）的等效模型。基于等价性，DHN中的所有状态变量都由热发电明确表示，并且DHN的可行区域投影在IEHS的耦合边界上。在温和的充分条件下证明了该等效模型的存在。通过IEHS的分布式单位承诺，证明了提出的等效模型的应用。
