Abstract

With the growing number and capacity of photovoltaic installations connected to distribution networks, power quality issues related to voltage regulation, are becoming relevant problems for power distribution companies and for PV owners. In this context, the paper investigates on unintentional disconnection of photovoltaic plants connected to weak low voltage distribution network. Measurement results put in evidence frequently disconnections of the photovoltaic system, related to relevant voltage fluctuations at the connection point of the active customer, during the operation of its photovoltaic system.
