Abstract: The aim of this letter is to present a universal power quality conditioning system (UPQS) named after unified power quality conditioner (UPQC), which is extended by adding a shunt active filter at the load side. Its main purpose...

The power quality improvement becomes one of the important tasks while using microgrid as main supply. Because is combination renewable energy resources. resources are intermittent in supply and at peak loading condition it has to required power. So, problems may increase that time. Out all issues voltage drop harmonic distortion considered most serious one. In recent years unified conditioner ...

This paper presents unified power quality conditioner (UPQC) system based on three-level neutral point clamped (NPC) using Fuzzy and ANN controllers. The proposed UPQC is able to mitigate source current harmonics compensate all voltage disturbances. It designed by the integration of series shunt active filters (AFs) sharing a common DC bus capacitor. maintained constant proportional integral co...

Voltage sag/swell is one of the most frequently power quality problems which affects the power systems with sensitive loads. The unified power quality conditioner (UPQC) is capable of mitigating the effect of voltage sag/swell at the load or point of common coupling (PCC). In this paper, a new control of UPQC is proposed based on combining the sag detection and voltage injection established on ...

Power quality (PQ) assurance is a vital part of electrical distribution networks. There are many advantages and benefits improving PQ, especially in the modern/smart grid. Smart grid (SG) has lot complicated sensitive components (non-linear loads) addition to renewable energy systems (wind-solar) that may also be source PQ disturbances. problems harm personal life national production. Static sy...

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...
