Abstract :
This paper investigates the impact of two types of inverter-based distributed generation (DG) interface controllers on the Sandia frequency shift (SFS) antiislanding method. The antiislanding detection performance of the constant power-controlled DG and the constant-current controlled DG are compared and analyzed when the inverters are equipped with the SFS scheme. The comparison results show that the power regulator of the constant power-controller can degrade the SFS efficiency.
