This study aims to improve the low-voltage ride-through (LVRT) capabilities of wind power plants (WPPs) during various types of grid faults, such as line-to-ground (L-G), double line-to-ground (LL-G), line-to-line (L-L), and three-phase-to-ground (LL

Large-scale energy storage systems (ESSs) that can react quickly to energy fluctuations and store excess energy are required to increase the reliability of electricity grids that rely heavily on renewable energy sources (RESs). Hybrid systems, which

In this paper, a developed arc model is introduced using MALAB. The developed arc model interacts with the transmission network under investigation and shows the dynamic behaviour of primary and secondary arc stages. The arc is modelled using a time-

Accurate location of faults on overhead power lines for inspection-repair purposes is of vital importance for operators and the utility staff. This paper presents a new method for accurate location of faults on two ended and three ended (teed) transm

This paper describes a novel technique to eliminate the effect of decaying direct current (DC) component on DFT based phasor estimation. This technique is based on estimating the phasor of a sinusoidal wave corrupted by a DC component at an instant o

In the literature, wavelet techniques are proposed for the analysis of power system transients. Many mother wavelets have been used for this analysis such as Haar, Daubechies (db), Symlets, and Coiflets. This paper describes a strategy to choose a su

The technique for identifying fault types on single circuit lines, suggested by Ferrero et al. (1993) is modified to be suitable for protecting double circuit lines. The modified technique is based on estimating the Fourier coefficients of double cir
