Power grid simulation models for the energy transformation

Starting with the ENSTO-E transmission grid for the Central Europe (CE) interconnected region, the model parts extend to typical low-voltage distribution grids of residential areas in Karlsruhe. The KIT Campus-Nord as a real-laboratory grid model, as well as the 110 kV grid level of the zones Baden-Württemberg and Schleswig-Holstein were also modeled with high detail.  The models exist in the variants today (2022), according to NEP-2035 and target grid (2045). All simulations allow load flow studies, quasi-dynamic time series calculations, as well as transient-dynamic short-term studies of load changes as RMS or EMT analyses. By combining the models across all voltage levels, a "re-bundling" of the networks is possible, which is not possible for the network operators themselves - due to the EU competition rules on "un-bundling". The network models form an important building block for further HIL and PHIL experiments in the Energy Lab 2.0. In addition, the high-performance computers of the EGSAL laboratory (RTDS and Opal-RT hardware) were coupled with the real laboratories in Jülich (FZJ) and Oldenburg (DLR) to form a distributed real-time simulation.
