Modelling of Low-Voltage Grids with the Help of Open Data

In many studies on the expansion and optimization of low-voltage grids for the integration of additional loads or distributed generation there is a need for extensive georeferenced grid data. In the first part of this paper a refinement and enhancement of a fully automated method for the modelling of these data from OpenStreetMap and further sources will be presented, so that a large number of synthetic low-voltage grids can be created easily. The second part introduces an optimization procedure to distribute the grid connected buildings to the substations via line sections.
