The dataset gives data of two real* and two theoretical low voltage grids in European grid type. The real grids include a typical rural (59% cable share, long feeders, radial structure, small transformer) and a typical urban (96% cable share, short feeders, radial structure, large transformer) low voltage grid. The theoretical grids consist of a distribution transformer and one feeder, one is realized with cable feeder and the other with overhead line feeder.

Included are for each grid:
• Topology of low voltage grid,
• current ratings, lengths, and positive-sequence resistances, reactances and capacitances of line segments,
• connection points of customers,
• connection points of inductive devices,
• distribution transformer rated apparent power, nominal primary and secondary voltages, and positive-sequence resistance and reactance, and
• a solved load flow case.

*The exact location of both real grids cannot be published due to data protection issues.
