In Europe and other regions of the world, heat and power sectors are highly coupled. Thus, both sectors are interdependent which poses a challenge when modeling these systems. This paper presents a novel and integrated model framework to analyze coupled heat and power sectors. Said framework is designed to assess large-scale/multi-national systems such as the European continent’s one. The integral model character derives from a model sequence that first models heat demand at individual district heating network level, then determines the heat supply schedules of individual heat generation units in these networks and finally uses an extended version of a pre-existing large-scale market model, the WILMAR Joint Market Model, for electricity market simulations. All models are embedded in a common database environment. In order to validate the model framework, a historical year is chosen, and model outputs are compared to historical market outcomes. For comparison, two alternative, frequently used modeling approaches are equally tested. Results show that the developed model framework is far superior to the alternative modeling approaches. This statement concerns the reproduction of heat demands, power plant dispatch, electricity prices and net electricity exports. The results also suggest that the developed model can yield improved intra-zonal exchange schedules, which are one major driver for congested transmission network elements.

在欧洲和世界其他地区，热力和电力部门高度耦合。因此，这两个部门是相互依存的，在对这些系统进行建模时提出了挑战。本文提出了一个新颖的综合模型框架来分析热电联产。所述框架旨在评估大规模/跨国系统，例如欧洲大陆的系统。整体模型特征源自一个模型序列，该模型序列首先对各个区域供热网络级别的供热进行建模，然后确定这些网络中各个供热机组的供热时间表，最后使用先前存在的大型市场的扩展版本模型，WILMAR联合市场模型，用于电力市场模拟。所有模型都嵌入在通用数据库环境中。为了验证模型框架，选择了历史年份，并将模型输出与历史市场结果进行比较。为了进行比较，对两种常用的替代建模方法进行了同样的测试。结果表明，所开发的模型框架远远优于其他建模方法。该声明涉及热量需求的再生产，发电厂调度，电价和净电力出口。结果还表明，开发的模型可以产生改进的区域内交换计划，这是导致拥塞的传输网络元素的主要驱动力。结果表明，所开发的模型框架远远优于其他建模方法。该声明涉及热量需求的再生产，发电厂调度，电价和净电力出口。结果还表明，开发的模型可以产生改进的区域内交换计划，这是导致拥塞的传输网络元素的主要驱动力。结果表明，所开发的模型框架远远优于其他建模方法。该声明涉及热量需求的再生产，发电厂调度，电价和净电力出口。结果还表明，开发的模型可以产生改进的区域内交换计划，这是导致拥塞的传输网络元素的主要驱动力。
