Impact of Rooftop Photovoltaics on the Distribution System

When PVs operate under a unity power factor, the active power flowing through the lines would be correlated with the PV penetration level. As PV penetration increases, active power flow decreases initially until PV power becomes close to the load level, after which an increase in PV penetration would increase the power flow in the lines again.
