Abstract: Integrated Energy Systems (IES) with the coupling of electricity, gas and heat are assumed to be a suitable concept for future energy systems. For the necessary energy system analysis with respect to dynamics and stability, powerful tools are needed. Such tools should be provided in open toolboxes to make the research more transparent, comprehensive and communicative. It is aimed that scientists collaborate on models for multimodal energy system analysis. The dynamic simulation is a method that allows to consider transient, non-linear effects and controller design. The TransiEnt Library, developed and established at Hamburg University of Technology (TUHH), offers such a toolbox. Previous versions of the library worked with limited electrical models. In this paper, the extension of the TransiEnt Library with new models, that allow to consider stability effects of the electric grid, is described. To do so, features from Modelica® and its specification are used to create an advanced framework for the electrical part of IES. As a result, IES with interconnected electric grids can be modeled and simulated more precisely.
