A Hosting Capacity Assessment Method for Distributed PV Considering Inverter Voltage Control

Over-voltage is the major concern of constraint when assessing the maximum PV that can be integrated into the distribution network. A hosting capacity calculation methodology considering PV inverter voltage control based on fair rule is proposed in this paper. The method utilizes a dual binary searching algorithm in which the PV capacity and reaction power output of inverter are both changed iteratively. Using a testing distribution network, the proposed method is compared with other typical methods based on stepwise searching strategy and constant-power-factor inverter control mode. The precision and computational effectiveness of the proposed method is thus verified through comparison results.
