Heat pumps in district heating networks [PDF]
, 2013 In the current Danish energy system, the majority of electricity and heat is produced in combined heat and power plants. With increasing shares of intermittent renewable power production, it becomes a challenging task to match power and heat production, as heat demand and production capacity constraints limit the power plants.

Analysis of District Heating Networks
Applied Mathematics & Optimization, 2023 AbstractIn the context of district heating networks we consider a model for the distribution of energy through water (for heating or cooling) from a central power station to the consumers. We prove the well posedness of the system, by using the Banach Fixed Point Theorem together with stability estimates for reduced systems.

Challenges for District Heating in Poland
Discover Energy, 2023 Currently, the district heating (DH) in Poland is facing many challenges. The business model used hitherto was very simple—in most cities, heating plants produced heat, and centralized heating systems supplied the "product" at a price approved annually by the president of the Energy Regulatory Office (URE).

Landscape of district heating systems in Germany – Status quo and categorization
Energy Conversion and Management: X, 2021 Studies on decarbonizing district heating systems are either system specific or use artificial district heating systems. In contrast to the liberalized electricity sector, there are no disclosure obligations in the district heating sector.
