| 摘要: |
| 热网热损特性作为热力系统温度动态过程的重要驱动因素，在电热联合调度中受热网管道铺设方式的影响显著。针对不同的热网管道铺设方式，分析了热网热损特性在电热联合调度中的作用机理，以及在不同热网管道铺设方式下的特性差异，提出了一种计及热损特性影响的热网管道温度动态过程约束模型。基于此，计及风电出力与负荷的不确定性，建立了考虑热网管道铺设方式影响的多场景电热耦合系统调度模型及其信息间隙鲁棒优化求解策略。算例仿真结果表明：相比于传统管道约束模型，所提出的管道约束模型反映了热网实际结构对于热力系统运行约束的影响，提高了系统运行的经济性。 |

| Abstract: |
| As an important driving factor of the temperature dynamic process in the heating system, the heating loss characteristics of heating network are significantly affected by the laying method of heating network pipeline in the combined electric-thermal dispatching. Aiming at the different laying methods of heating network pipeline, the mechanism of heating loss characteristics of heating network in the combined electric-thermal dispatching and the characteristic differences under different laying methods of heating network pipeline are analyzed. A dynamic process constraint model of heating network pipeline temperature considering the influence of heating loss characteristics is proposed. On this basis, considering the uncertainties of wind power output and load, the dispatching model of multi-scene electric-thermal coupling system considering the influence of laying method of heating network pipeline is established, and the robust optimization solution strategy with information gap is proposed. The simulative results of case study show that compared with the traditional pipeline constraint model, the proposed pipeline constraint model reflects the influence of the actual structure of heating network on the operation constraints of heating system, and improves the operation economy of system. |
