AbstractCoordination 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.
