Abstract

The aim of this thesis is to integrate a detailed model of the Austrian electricity transmission network into an existing Europe-wide energy system model. By increasing the spatial and structural resolution of Austria¿s transmission grid, the model enables more accurate analysis of regional power flows, security of supply, and infrastructure development. At the same time, the consistency of the overarching European model is preserved to allow for the investigation of continent-wide scenarios. As part of this work, the Austrian power grid was reconstructed from various datasets. This included digital grid data sourced from geospatial files stored in a database. The data were processed using geographic information systems, harmonized, and converted into a network-compatible format. The processing steps included, among others, the definition of a unified coordinate system, the transformation of geometries into network components, and the standardized mapping of node and line information. A key component of the thesis is the development of an automated modeling workflow. This workflow was implemented using a flexible workflow management framework, enabling easy reuse and adaptation to different scenarios. The integration of the Austrian grid into the European model is carried out through spatial alignment of grid nodes. Where interconnections at national borders are missing, they are added algorithmically. Furthermore, a method was developed to distribute time-varying electricity demand profiles across the Austrian grid nodes, based on existing time series representing renewable energy generation. The main result is a fully integrated, high-resolution Austrian grid model embedded within a European energy system framework. Thanks to the automated approach, the workflow is transferable and reproducible. It provides a solid foundation for further analyses in grid planning, supply security, and energy transition scenarios, with a particular focus on Austria within the broader European context.
