Balancing DSO interests and PV system economics with alternative tariffs

Christophe Ballif, Alejandro Pena Bello, Robin Junod

Distributed rooftop photovoltaics (PV) is one of the pillars of the energy transition yet their widespread integration strains grids, leading to over-voltage, reverse power flow, and infrastructure strain. Furthermore, increased PV self-consumption reduces ...
