Development and modeling of different scenarios for a smart distribution grid

This paper presents a low-voltage distribution grid model designed for a future smart grid based on real data. The grid model is built measuring the distribution lines´ length and considering the cable dimensions and lengths, the grid age, the number of cabinets and customers and the load per customer. The aim of the model is to design, implement and test the proposed configuration and to investigate whether the low-voltage distributed grid is prepared for the expected future increase of PV penetration with heat pumps and electric cars connected along the feeders. The model is implemented in NEPLAN and Power Factory and different scenarios will be developed and analyzed. A time series simulation will also be presented for a specific scenario with a comparison between different voltage profiles along the feeder.
