Generating Low Voltage Grids on the Basis of Public Available Map Data

Being subject of historic growth and focusing on the load supply in the past, only few low voltage grid models are available for research purposes. Due to energy system changes with large amounts of renewable feed-in being redistributed within these grids, it becomes more important to create a reliable data basis to evaluate innovative control approaches. Facing this lack of data, in this paper, low voltage grids are constructed on the basis of public available geographical data from OpenStreetMaps (OSM) for selected residential areas. The presented approach includes the definition of the supply task in the study region, the positioning of low voltage substations and a fitness evaluation of the generated network to optimize the positioning process. In comparison to real network data it is demonstrated, that the proposed approach provides reasonable approximation of the real network for research purposes.
