Future electricity flows and their impact on the power distribution grid on a decentralized level

The increasing electrification of the heating and the transportation sector requires a long-term analysis regarding potential grid infrastructure adjustments. In the presented study, an approach for bottom-up household-load profiles (including photovoltaic profiles) is enriched with charging patterns from electric vehicles, generated by the travel demand model mobiTopp and used for a quasi-dynamic grid analysis on a low-voltage level. As a result, the need to expand the low-voltage power grid and the expected costs are identified. Finally, flexibility measures for load shifting are implemented, and their effects on the need for expansion are examined.
