The project focuses on decentralized feed-in of heat into district heating networks. The first step of the research work is to modell or simulate volatile suppliers. The models and profiles developed characterize the variability of the practically relevant values over time, e. g. the mass flow rate and temperature of the heat feed into district heating networks. These models are then coupled to different simulation models for district heating systems. This way, the current and future effects of increasing numbers of decentralized heat sources can be assessed.
On the basis of existing district heating networks, these effects are modelled under different climate conditions. Via simulation studies, the effects on (primary) energy consumptions and the technical boundary conditions can be identified and sensible storage integration solutions proposed. The analysis comprises also an evaluation of the impact on the system efficiency and gives indicators on the economics of the district heating systems.
