Single phase unified power quality conditioner (UPQC) consists of series and shunt active power filter (APF) with common dccapacitor. Series converter acts as voltage source converter and shunt converter acts as current source converter. Use of non-linear loads results in voltage and current harmonics. These harmonics can be eliminated by using single phase UPQC. So that, which also improves th...

This paper presents an improved controller for the dual topology of the unified power quality conditioner (iUPQC) extending its applicability in power-quality compensation, as well as in micro grid applications. By using this controller, beyond the conventional UPQC power quality features, including voltage sag/swell compensation, the iUPQC will also provide reactive power support to regulate n...

This paper presents a new control method for a three-phase four-wire Unified Power Quality Conditioner (UPQC) to deal with the problems of power quality under distortional and unbalanced load conditions. The proposed control approach is the combination of instantaneous power theory and Synchronous Reference Frame (SRF) theory which is optimized by using a self-tuning filter (STF) and without us...

This article offers a power quality (PQ) strategy to reduce light intensity flickers, voltage enhancements, and harmonics mitigation of the grid current in extensive networks LED lighting at Cairo airport, Egypt. A transformerless unified conditioner (TL-UPQC) with its controls is presented address majority PQ issues network. The TL-UPQC comprises dynamic restorer (DVR) as series compensator, w...

<span lang="EN-US">The intensive use of non-linear loads is further contributing in the increase power quality problems. They cause voltage distortions and current harmonics an electrical distribution network. To minimize these problems, unified conditioner (UPQC) used. The intermediate circuit this filter can deviate from its source during a transient event harmonic disturbance (voltage ...

The Unified Power Quality Conditioner (UPQC) is a technology that has successfully addressed power quality issues. In this paper, photovoltaic system with battery storage powered presented. Total harmonic distortion of the grid current during extreme voltage sag and swell conditions more than 5% when UPQC controlled synchronous reference frame theory (SRF) instantaneous reactive (PQ) control. s...
