Co-simulation Workflow for the Dynamic Modelling and Simulation of Large-scale District Energy Systems

Research output: Chapter in Book/Report/Conference proceedingConference contribution


With the increasing complexity of urban energy systems,
the requirements for modelling and simulation methods
have increased. Co-simulation is a promising approach
for carrying out system simulations, in which the
respective sub systems are modelled using tailored tools.
This paper presents a workflow for dynamic simulation of
large-scale district energy systems introducing three main
improvements compared to the state of the art: i) The data
preparation was carried out using Vectorworks and QGIS;
ii) A novel pipe-laying algorithm with grid dimensioning
is introduced; iii) A co-simulation framework was applied
to assess energy supply variations. The tools Dymola,
IDA ICE and TRNSYS are thus coupled using cosimulation. The framework was applied on a virtual
district: Different energy supply strategies were compared
and the temperature increase due to global warming on
the energy supply was investigated.
