- •
A novel matrix model of district heating network was proposed.
- •
Thermal conditions can be solved analytically and efficiently by matrix operation.
- •
The number of uncertain parameters was reduced by an aggregation operation.
- •
Model parameters were calibrated by an optimized method using genetic algorithms.
- •
After calibration, predicted temperatures fitted well with measured data.
