Innovative control system for district heating networks
With the "AD Net Heat" software, Fraunhofer researchers are developing a solution that makes district heating networks more efficient and climate-friendly. With the help of a digital twin, heat flows can be simulated, peak loads can be forecast and networks can be optimally controlled - an important step towards a CO₂-neutral energy supply.
The energy transition poses challenges for district heating networks, as the feed-in of renewable energies and decentralisation make efficient control more complex. With its simulation software, the Fraunhofer Institute ITWM offers a solution that can monitor, stabilise and optimise grids in real time.
Digital twin for precise control
The core of the innovation is a digital twin that simulates the physical processes of the grid. Basic data such as grid structure, weather and consumption data are incorporated into the simulation in order to recognise heat flows, load peaks and critical operating states at an early stage. Municipal utilities benefit from more stable network operation and can reduce unnecessary energy losses by optimising flow temperatures.
Increased efficiency in planning and operation
The software enables forward-looking planning of new grids. Scenarios such as the placement of energy sources or consumption at different times are simulated in order to utilise resources efficiently. Material savings through smaller pipe cross-sections and the precise utilisation of renewable energies reduce costs and promote a climate-neutral heat supply.
Future-oriented extensions
In addition to optimising the user interface, the researchers are also working on making the software’s calculation core usable for other energy networks such as electricity and gas. This could make “AD Net Heat” a model for the digitalisation of other infrastructure projects.
