Harvesting the ﬂexibility of energy communities from a DSO perspective

Antoine Zürcher

As non-controllable power sources, photovoltaics can create overvoltage and overloading in low voltage (LV) distribution feeders during periods of high generation and low demand. This is usually prevented passively by limiting the penetration level of PV t ...
