Research on Detection Technology of Islanding Effect in the Photovoltaic Grid-Connected Power Generation System

The islanding effect is one of the main problems caused by photovoltaic grid-connected power generation technology. Currently, most photovoltaic power plants use active frequency offset detection methods to detect islanding effects. Still, this method interferes with the output power quality, but its detection efficiency is greatly affected by the load. In this paper, the drawbacks of the active f...
