Speerforck, ArneArneSpeerforckVieth, JonathanJonathanViethWestphal, JanJanWestphal2026-07-022026-07-022026-0220th MODPROD Workshop 2026https://hdl.handle.net/11420/63701In this publication, a tool chain from heat-demand and geolocation data to an executable Modelica simulation is presented. The emphasis is on the network generation based on a shortest path algorithm, as well as on the modeling concept of the dynamic simulation. It can be shown that large-scale DHN can be simulated with Modelica. Moreover, the automatic development of those models significantly reduces operational effort.enhttps://creativecommons.org/licenses/by-sa/4.0/Technology::621: Applied PhysicsConference Presentation10.3384/wcc3810.15480/882.17394
