An active islanding detection method based on frequency-locked loop (FLL) for constant power controlled inverter in single-phase microgrid is proposed. This method generates a phase shift comparing the instantaneous frequency obtained from FLL unit w

A shifting window average method (SWAM) is proposed for phasor measurement at offnominal frequencies. The proposed SWAM is not only applicable for fundamental frequency phasor measurement, but also for harmonic phasor measurement as well. SWAM is bas

A consecutive DFT method for instantaneous oscillating phasor measurement is proposed in this paper. The proposed method is based on one cycle DFT and applies three consecutive DFT values for phasor measurement. First, an analysis of standard DFT bas

A novel algorithm based on discrete Fourier transform (DFT) to estimate the frequency of power system is proposed. The algorithm that we called transformed discrete Fourier transform (TDFT) involves transforming consecutive points of DFT of voltage s

Taking advantage of S-transforms (STs), this paper proposes a new method of detecting and classifying power-quality disturbances. The ST is unique in that it provides frequency-dependent resolution while maintaining a direct relationship with the Fou

Droop control strategy is widely used in autonomous control of microgrid. As resistance is the main characteristic of low-voltage microgrid, the P-V droop control method was used in VSI active power distributing to provide voltage support for grid. A
