Investigation of the interaction between step voltage regulators and large‐scale photovoltaic systems regarding voltage regulation and unbalance [PDF]
IET Renewable Power Generation, 2016 The number of installed photovoltaic (PV) systems has been increasing in an unprecedented rate every year throughout the world. In some situations, the PV systems can provide more power than the demand in certain parts of a network and cause reverse power flow, which the traditional distribution networks are not designed for.
