Threats to stability and security of the electric grid are not limited to one voltage level, but can form complex event cascades across multiple network levels. Furthermore, the structure of the local grid as well as the composition of customers have a significant influence on the characteristics of the incidents. High-resolution, interconnected grid models are therefore required for detailed investigations of current and future threats like temporary overvoltages. Here we present an approach to produce and combine synthetic high voltage (HV) and medium voltage (MV) grid models based on the actual supply task of German grids. The supply task can be inferred by open data approaches, e.g., high spatial satellite data and register databases. The resulting grids reproduce local characteristics and can form a basis for grid stability studies.
