The increasing digital transformation in energy supply systems allowsgreater control and possibilities for performance optimization and efficiency.This is accompanied by increasing complexity of the system, and thus requiresthe evaluation of interactions between energy and information andcommunication technologies (ICT) involved. One of the goals of the project“Zukunftslabor Energie” (Future Laboratory “Digitalization Energy”) is toanalyze these interactions in highly integrated digitalized systems for districtenergy supply. For this, simulation studies must be conducted to configureflexibilities. A first step is to define appropriate analysis scenarios. Requirementsfor these scenarios, the related models, and one of the considered scenarios aredescribed in this paper. This allows to discuss the system, its boundaries, itscomponents, and their interactions. Future research requires an analysis anddiscussion of requirement specifications, data collection and treatment, modelconstruction, model implementation, and model validation.
