An Active Islanding Detection Method for Grid-Connected Renewable Energy Generation System

Article Preview

Abstract:

This study proposes an active islanding detection method for use of grid-connected inverter of renewable energy generation system (REGS). With a digital signal processor (DSP) integrated, the proposed method is capable of detecting the islanding fault of grid-connected inverters of REGS during the variable load conditions. To verify the effectiveness of the proposed method, the method was tested on a practical inverter of REGS, the field practical operations of the proposed method were studied in accordance with the conditions for the different loads and fault types. Test results are presented which show that the new proposed method is reliable, economical and easy for implementation.
