The integration of a large amount of Photovoltaic could be an issue due to the excess of power generation and the ability of the low-voltage grids to extract the energy to the upper level. Appropriate tariff structures could prevent the need for grid reinforcements while ensuring an adequate payback time for the prosumers. This work aims at estimating the potential of advanced electricity tariff structures to mitigate the impact of photovoltaics in distribution grids.
