In this paper, based on a benchmark the performance of Unified Power Quality Conditioner (UPQC), improvement is presented comparatively by using Proportional Integrator (PI)-type controllers optimized Grey Wolf Optimization (GWO) computational intelligence method, fractional order (FO)-type differential and integral calculus, PI-type controller in tandem with Reinforcement Learning—Twin-Delayed...

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...

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...

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...

This paper presents novel Unified Power Quality Conditioner (UPQC) system based on seven-level Neutral Point Clamped (NPC) inverter using combined PD-SPWM and fuzzy control scheme. The proposed UPQC is adopted to mitigate source current harmonics compensate all voltage disturbances simultaneously. It designed by the combination of series shunt Active Filters (AFs) connected a common DC link cap...

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...

One of the major concerns in electricity industry today is power quality. It becomes especially important with the introduction of advanced and complicated devices, whose performance is very sensitive to the quality of power supply. The electronic devices are very sensitive to disturbances and thus industrial loads become less tolerant to power quality problems such as voltage dips, voltage sag...

Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current disturbances that could affect sensitive electrical loads while compensating the load reactive power. Diverse control techniques have been proposed to evaluate the instantaneous output voltage of the series active power filter of the UPQC but, in most cases, these controllers only can compensate a kind of vol...

The current power sector is dealing with the poor power quality issues and the reason behind this poor power quality is voltage fluctuations, harmonics, transients and reactive power demands and these problems arises due to changing trend of our demand. Nowadays in our demand the share of power from power electronic devices has increase a lot and also coupling of grids to wind farms and solar f...
