conclusion A load flow simulation result shows that 690kWp can fit well with power flow and voltage variation of the grid The optimal capacity of the PV installed at BUS 4 analyzed in this study is 1400kWp, which generates a maximum NPV of around $4.31million. It’s PBY is around 13 years. An estimated annual rejected PV power of this aforementioned optimal capacity is around 345MWh.
