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 many residential and commercial low voltage (LV) networks, three-phase four-wire
distribution systems are used to accommodate single-and three-phase customer loads and …

This paper deals with improving the voltage quality of sensitive loads from voltage sags
using a dynamic voltage restorer (DVR). The higher active power requirement associated …

This paper deals with the protection of critical loads from voltage-related power quality
issues using a dynamic voltage restorer (DVR). A generalized control algorithm based on …

Renewable energy sources; which are abundant in nature and climate friendly are the only
preferable choice of the world to provide green energy. The limitation of most renewable …

This paper proposes a modified pq-theory-based control of a solar photovoltaic (PV)-array-
integrated unified power quality conditioner (PV-UPQC-S). The system incorporates clean …

In this paper, an alternative control method is proposed to improve the harmonic
suppression efficiency of the active power filter in a distorted and an unbalanced power …

This study examines the use of superconducting magnetic and battery hybrid energy storage
to compensate grid voltage fluctuations. The superconducting magnetic energy storage …

Controlled and improved power quality is one of the fundamental and essential needs in any
industry driven by electric power for optimal exploitation of resources. However, in power …

This article presents a super twisting sliding-mode control (ST-SMC) for single-phase
dynamic voltage restorers (DVRs). Unlike the conventional first-order sliding-mode …
