Abstract

In recent years, it has been discovered that the magnitude of the connection node voltage is affected by the output power from a photovoltaic (PV) generator and the line impedance when the PV generator, in an increasing trend, is introduced into the distribution system. In this paper, power flow is qualitatively discussed using basic circuit theory comprising the voltage and current vector diagram. A magnitude and its operation point of the maximum allowable output power from the PV generator were successfully derived in the vector diagram where the power conditioning system was operated with a constant output power and constant power factor controls. Furthermore, an optimum capacity of the PV generator was also clarified in the vector diagram to effectively utilize the output power of the PV generator.
