Impact of photovoltaic rooftop scale penetration increasing on low voltage power systems

As PV penetration levels increased, its impact on electric power systems has attracted attentions worldwide. This paper presents analytical and experimental studies. Effects of the low-voltage grid-connected PV systems in rooftop scale are experimentally studied. The results represent the impact on point of interconnection in low voltage distribution system. Then we show analytical study of simplified system to compare with the experiment results. The experimental results have shown an agreement with the analytical study.
