Coordinated operation of Coupled Electric Power and District Heating Networks (CEPDHNs) brings advantages as e.g., the district heating networks can provide flexibility to the electric power network, and the entire system operation can be further decarbonized through heat pumps and electric boilers using electricity from renewable energy sources. Still, today CEPDHNs are often not operated in a coordinated way causing a lack of efficiency. This paper shows, how efficient resource allocation is achieved by determining the power exchange between both networks over an aggregated market. We introduce a welfare-optimizing, market-based operation for a CEPDHN that satisfies operational constraints and considers network losses. The objective is to integrate uniform pricing market-clearing and operational constraints into one approach, in order to obtain high incentive compatibility for the market participants while preventing high uplift costs from redispatch. For this, we use a hybrid market model mainly based on uniform marginal pricing and additionally utilize pay-as-bid pricing for a fraction of the allocated bids and offers. We perform a case study with a real CEPDHN to validate the functionality of the developed approach. The results show that our solution leads to efficient resource allocation while maintaining safe network operation and preventing uplift costs due to redispatch.

电力和区域供热耦合网络 (CEPDHN) 的协调运行带来了优势，例如，区域供热网络可以为电力网络提供灵活性，并且可以通过使用可再生电力的热泵和电锅炉使整个系统运行进一步脱碳能源。尽管如此，今天的 CEPDHN 通常没有以协调的方式运行，从而导致效率低下。本文展示了如何通过确定聚合市场上两个网络之间的电力交换来实现高效的资源分配。我们为 CEPDHN 引入了一种福利优化、基于市场的操作，它满足操作约束并考虑网络损失。目标是将统一定价的市场出清和操作约束整合到一种方法中，为市场参与者获得高激励兼容性，同时防止重新调度带来的高昂提升成本。为此，我们使用主要基于统一边际定价的混合市场模型，并另外对分配的出价和报价的一小部分使用按出价定价。我们使用真实的 CEPDHN 进行案例研究，以验证所开发方法的功能。结果表明，我们的解决方案可实现高效的资源分配，同时保持安全的网络运行并防止因重新调度而导致的成本上升。我们使用真实的 CEPDHN 进行案例研究，以验证所开发方法的功能。结果表明，我们的解决方案可实现高效的资源分配，同时保持安全的网络运行并防止因重新调度而导致的成本上升。我们使用真实的 CEPDHN 进行案例研究，以验证所开发方法的功能。结果表明，我们的解决方案可实现高效的资源分配，同时保持安全的网络运行并防止因重新调度而导致的成本上升。
