Local and district heating networks have a wide range of highly developed electronics that enable remote monitoring, control and additional services for the heating systems. There are different software and hardware applications at different levels with different formats and interfaces that work without communicating with each other.
The REM / REC / RES project examined the feasibility of a higher-level energy management system for small and medium-sized heating networks. The data collection was carried out at two selected heating plants. The components of the existing systems and possible extensions to existing heat sources were examined. The available data was integrated into a database programmed for this purpose and was thus available in a further processable form for simulations and optimizations. When simulating the entire network in MATLAB / Simulink, scenarios were calculated on the one hand that lead to an improvement in the overall efficiency of the heating system and, on the other hand, integrating locally available additional heat sources in order to find the sustainable optimum for the heating network.
On the basis of the parameters used and the calculation results, by determining the expected system costs and savings potential, no short-term economic introduction of a higher-level energy management system can be assumed. Further investigations and adaptations of the model can with high probability identify further savings potential and contribute to the development and implementation of a higher-level energy management system for small and medium-sized heating networks.
