FlexiGIS – Optimisation framework for urban energy systems

The open source optimisation framework for urban energy systems FlexiGIS (Flexibilisation in Geographic Information System) uses publicly available data sets to map, classify and model urban energy infrastructures, prioritising georeferenced data. These datasets include, for example, building areas, roadways or information on land use. FlexiGIS supplements these data sets with modelled data, for example on the electricity requirements of individual buildings, by taking into account various characteristics such as building age or population data. Furthermore, an optimisation environment makes it possible to calculate the most economically cost-effective use of different technologies while ensuring security of energy supply. Any limitations of technologies, for example due to a lack of expansion areas, are taken into account as boundary conditions. By mapping and evaluating different development scenarios for the urban energy system, the degree of regional self-sufficiency and flexibility potential can also be quantified.
