One of the issues that arise when a large number of PV systems are installed is the phenomenon of voltage fluctuations in the distribution system, and it is known that reverse power flow from PV systems can cause voltage rises and drops in the distribution system. The authors have also proposed a method using the area on a vector diagram as an analysis method for the effective power.

In this paper, by focusing on a different area on the vector diagram, it is clarified that the value of the area can be expressed as the active and reactive power as it is, and the maximum value of each active and reactive power in this case is obtained.
