Optimisation of district heating production by utilising the storage capacity of a district heating network on the basis of weather forecasts

Seasons cause large variations in heating demand for buildings, and the heat is produced district (DH) with several production plants. The network itself can be assimilated to a thermal energy storage unit used effectively peak reduction purposes. balances operation of system, which allows smoother running entire process. Short- long-term enables transition current systems towards next generation low-temperature DH sustainable multi-energy networks. In this study, an example system two 4 MW boilers, located Kymenlaakso, Finland was studied. use optimised by charging via adjusting supply water temperature instead using reserve power. savings potential depends on at interface where power would have introduced, size volume, increase temperature. On basis weather forecasts 15 K, received could been 185 MWh emissions 40 tCO2 renewable recycling-based wood fuels during years 2018–2020 environmentally friendly case network.
