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 …

This paper reviews the basics of series compensation in transmission systems through a
literature survey. The benefits that this technology brings to enhance the steady state and …

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 …

This paper presents a new open-loop architecture for three-phase grid synchronization
based on moving average and predictive filters, where accurate measurements of phase …

For the effective operation of a dynamic voltage restorer (DVR), a control strategy plays a
significant role. This paper presents an enhanced control strategy for DVR using dual role …

In this paper, a three-phase three-wire dynamic voltage restorer (DVR) system has been
chosen with quasi-Newton (QN) filter-based control algorithm. It uses Hessian matrix …

This article investigates a single-phase ac-dc-ac multilevel converter composed of two three-
leg converters series-connected throughout two transformers (one on the grid side and one …

To control power flow and manage fault level in meshed MV networks, back-to-back voltage
source converters (B2B-VSCs) are being used. However, their high cost and relatively low …

When connecting the grid-connected power electronics systems to the utility system, one of
the most important aspects to be considered is the synchronization with the grid system in …

The series active power filter seems an ideal device to improve power quality. It allows to
suppress and isolate voltage based distortion such as voltage unbalance, sag, interruption …
