Impact of Solar PV on Distribution Systems Embedded with Electric Vehicle

When 1-phase rooftop solar photovoltaic (PV) is also presented, the various consequences on the distribution system are explored via the charging of electric vehicles. The IEEE 37 test feeder has been modified to investigate several issues such as active and reactive power at the substation, active and reactive energy loss in the system, influence on distribution transformers and residential house voltages. When PVs are in the system, the power required from the substation is lowered during the day, with no influence on reactive power, and system losses are also reduced. When solar power is available, increasing PV does not affect distribution transformer unbalance, while increasing EV adoption reduces distribution transformer overload dramatically.
