Power quality is a pressing concern and of the utmost importance for advanced and high-
tech equipment in particular, whose performance relies heavily on the supply's quality …

During the last half century the Power Quality (PQ) related problems have become important
issues. Many solutions have been proposed to address the PQ problems. The most …

Recently utilities are continuously seeking cost-effective and accurate power quality (PQ)
improvement techniques in order to achieve customer satisfaction. This paper intends to …

This paper investigates the fault ride through (FRT) capability improvement of a doubly fed
induction generator (DFIG)-based wind turbine using a dynamic voltage restorer (DVR) …

In this paper, two new topologies are proposed for three-phase dynamic voltage restorers
(DVRs). These topologies are based on direct converters. The proposed topologies do not …

In this paper, a transformerless hybrid series active filter using a sliding-mode control
algorithm and a notch harmonic detection technique are implemented on a single-phase …

Voltage sag is a common and undesirable power quality phenomenon in the distribution
systems which puts sensitive loads under the risk. An effective solution to mitigate this …

This paper presents an optimized sliding mode control (SMC) strategy to maximize
existence region for single-phase dynamic voltage restorers. It is shown analytically that …

Cost of various energy storage technologies is decreasing rapidly and the integration of
these technologies into the power grid is becoming a reality with the advent of smart grid …

A novel control scheme for the dynamic voltage restorer (DVR) is proposed to achieve fast
response and effective sag compensation capabilities. The proposed method controls the …
