Solar Energy in Low Temperature District Heating

Optimal integration of solar energy in a district heating network

The implementation of European Directive 2012/27 calls for the presence of a renewable share inside efficient district heating and cooling. Solar thermal energy can be a viable contribution to this aim but particular attention must be put into its integration inside the district heating systems. In fact, the variable and non-controllable nature of renewable heating must be handled by fulfilling...

Solar District Heating with Seasonal Storage in Attenkirchen

Energy conservation through energy storage combined with intensive use of renewable energies will support the effort to meet the objectives of reduction of climatic gases formulated in the Kyoto protocol. Potential studies have shown that in Germany about 20 – 25 % of the end-energy consumption for space heating and domestic hot water can be covered by solar energy. Solar district heating with ...

Temperature Prediction in District Heating Systems with cFIR models

Current methodologies for the optimal operation of district heating systems are based on model predictive control. In complement to load forecasts, accurate predictions (up to 12-hour ahead) of the water temperature at critical points of the networks are crucial for meeting constraints related to consumers while minimizing the production costs for the heat supplier. The paper introduces a new f...

Temperature prediction at critical points in district heating systems

Current methodologies for the optimal operation of district heating systems use model predictive control. Accurate forecasting of the water temperature at critical points is crucial for meeting constraints related to consumers while minimizing the production costs for the heat supplier. A new forecasting methodology based on conditional Finite Impulse Response (cFIR) models is introduced, for w...
