Buildings and a district heating network as thermal energy storages in the district heating system

The analysis shows that a temperature of −18°C can be adopted as the reference to determine the expected heat output in the DHS. On this basis the heat output can be reduced for central heating by 1%. The energetic effect of use buildings and a district heating network as thermal energy storages to compensate the reduced heat output of the district heating system was 16.2 MW. The achieved equivalent heat output was 93.2 MW. Considering all solutions, the heat output can be reduced for central heating by 14.8%.
