In a future power system, it is very important to evaluate phenomenon called mutual smoothing effect, because cost of countermeasures to mitigate impact of highly penetrated PVs' fluctuation will depend on the effect. In the previous work, the authors developed a method called “Transfer Hypothesis” for presuming total output fluctuation of highly penetrated PVs considering mutual smoothing effect based on analyses of measured irradiance data in the spring time. In the method, parameter called “Transfer Swing Period” which is identified from measured irradiance data is important to represent smoothing effect. Therefore, if the transfer swing period has some trends depending on season, month or fluctuation condition, presumption results could be affected by how to select the transfer swing period. This paper shows a study on impact of the parameter (transfer swing periods) selection on presumed total output fluctuation of highly penetrated PVs and consideration for a future power system.
