Mitigating the impact of distributed PV in a low-voltage grid using electricity tariffs

Christophe Ballif, Nicolas Würsch, Lionel Benjamin Bloch, Jordan Holweger

A high share of distributed photovoltaic (PV) generation in low-voltage networks may lead to over-voltage, and line/transformer overloading. To mitigate these issues, we investigate how advanced electricity tariffs could ensure safe grid operation while en ...
