Zusammenfassung
A method for evaluating the operation characteristic of grid-connected
PV systems in multiple interconnection was proposed and a suppression
of PV electric energy which is reduced by an automatic voltage control
unit was estimated using a yearly scale simulation. The automatic
voltage control unit is one of the PV inverter functions. In Japan,
PV systems must be provided with this function to maintain within
101V76V for the standard voltage of 100V according to the technical
recommendations. The automatic control voltage unit adjusts the distribution-line
voltage at a connected point using leading reactive power or active
power. Especially, the adjustment of active power will cause a suppression
of PV electric energy.
