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 …

This paper describes a control algorithm based on modified enhanced phase-locked loop
(MEPLL) in dynamic voltage restorer (DVR). It compensates distortions and unbalances in …

This paper presents the mathematical basis to restructure the recursive-least-squares (RLS)
technique for real-time implementations on digital signal processors (DSPs). The proposed …

In this paper, we present two modulation schemes for generating unbalanced voltages by
means of four-leg voltage-source inverters. The first modulation is an extended scheme of a …

The dynamic voltage restorer (DVR) is a series compensator for distribution system
applications, which protects sensitive loads against voltage sags by fast voltage injection …

In this paper, a novel reference generation method based on Improved Synchronous
Reference Frame (ISRF) is presented for Dynamic Voltage Restorer (DVR). This method is …

This paper proposes the usage of a repetitive-based control to dynamically restore the
voltage applied to sensitive and critical loads of power system. The control intrinsically is …

This paper proposes a method for estimating the appropriate grid impedance for
applications in which distributed generators are connected to the grid through three-phase …

This paper proposes a frequency-adaptable method for computing the phase associated
with the positive sequence components from the measured grid voltages. It relies on a …
