Status of the TransiEnt Library: Transient Simulation of Complex Integrated Energy Systems

The open-source Modelica library TransiEnt Library was developed within the research project TransiEnt.EE. This paper presents two major extensions to this which were in follow-up ResiliEntEE. modeling of power sector on transmission grid level is possible due implementation complex bus voltage. In gas sector, efficiency computation mass and energy balances improved. Furthermore, an efficient physical pressure loss model added that leads more realistic results faster simulations. application are presented exemplary simulation integrated system. It shown dynamic allows depiction disturbances their consequences coupled sectors. Thus, next cost CO2 emission, system can be assessed terms its resilience as well.
