Grid modeling, analysis and simulation of different scenarios for a smart low-voltage distribution grid

This paper presents the modeling, analysis and simulation of a low-voltage distribution grid model based on the real data designed for evaluation of a future smart grid. 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 distribution grid is prepared for the expected future increase of PV penetration, heat pumps and electric cars. The model is implemented in NEPLAN and DIgSILENT Power Factory and different scenarios are developed and analyzed. A time series simulation is conducted for a specific scenario with a comparison between different voltage and load profiles along the feeders.
