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.
