Streszczenie
Evolution of energy market and development of IT result in new challenges for operational optimization in
modern district heating networks. Among the solutions which can help in such optimization, thermal load shifting with the
use of inertia of buildings has been identified as one which requires additional research. Two mathematical models for
simulation of transient behavior of buildings connected to DH systems have been described, and the more simplified model
has been validated by comparing results.
The simplified model for simulation of building’s behavior can be used in global operational optimization of DH systems,
and the methodology demonstrated in this article can help DH operators in assessing, what kind of power limitation can be
used under certain conditions for a group of buildings with certain properties, in order not to affect the comfort of the
customers nor make significant errors in simulation. The results can prove useful for DH system operators in the near future.
