Increase Photo Voltaic hosting capacity using datadriven network modeling

Abstract

It is frequently admitted that the rate of photo voltaic (PV) peak power must not exceed 20% to 30% of the maximum power consumed on a given LV feeder. As a result, the PV hosting capacity remains quite low, or the DSO takes the risk of voltage issue if he decides to exceed. RESA, the Belgian DSO and Odit-e, a French startup have tested a new way to at least double the PV hosting capacity of network feeders. An experimentation was made in an area already overequipped with PV and subject to voltage issues. Results show that it has been possible to tackle existing voltage issues efficiently and to identify a significant additional hosting capacity.
