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 …

In this paper, the elimination of harmonics in a cascade multilevel inverter by considering the
nonequality of separated dc sources by using particle swarm optimization is presented …

Transmission and distribution (T&D) networks are a critical part of the power grid. As moving
towards a smart-grid, it is essential to modernize the T&D networks and make it “Smart-grid …

Power quality difficulties arise as a result of Renewable Energy Sources (RES) integrating
with the grid. Voltage swell, sag, and harmonic distortion occur on the grid due to power …

Geomagnetic Disturbances (GMDs) are the result of solar storms or a high-altitude nuclear
detonation. On the power systems, they might lead to the flow of quasi-DC currents referred …

The dynamic voltage restorer (DVR) as a means of series compensation for mitigating the
effect of voltage sags has become established as a preferred approach for improving power …

This paper introduces a new configuration for a cascade (H-bridge) converter-based
dynamic voltage regulator in which the basic cascade converter is supplemented with a …

Dynamic voltage restorer (DVR) is a power electronic converter‐based custom power device
used to compensate for voltage variations. The inverter used in the DVR structure can have …

In this paper, the application of a cascaded multilevel inverter as a dynamic voltage restorer
(DVR) is investigated. Two discontinuous multilevel space vector modulation (SVM) …

This paper presents a new multilevel cascaded-type dynamic voltage restorer (MCDVR) with
a fault current-limiting function. This topology can operate in two operational modes: 1) a …
