Using PV in distribution network to supply local loads and power quality enhancement

The grid-connected photovoltaic (PV) power generation system is expected to be more widespread in distribution systems due to increasing fossil-fuel cost. This paper presents a control system that combines photovoltaic (PV) grid connected generation and power quality managements with two system configurations. The system can not only realize photovoltaic generation, but also suppress current harmonics and compensate reactive power.
