This suggested research work provided a distributed generator-based unified power quality conditioner with decreased rating and star-connected transformer as means of enhancing quality. The (UPQC), Y-connected transformer, an LC filter are all included in this work. When the source voltage is out balance, hybrids approach greatly enhance UPQC performance. that here intended to correct issues cu...

Different from the extant power flow analysis methods, this paper discusses flows for unified quality conditioner (UPQC) in three-phase four-wire systems point of view impedance matching. To end, combined with designed control strategies, establishing method UPQC model is presented, and on basis, system can be equivalent to an adjustable model. After that, a concept matching introduced into stu...

This work presents a distributed generation system (DG) that combines of wind turbine (WT) and photovoltaic (PV) using unified power quality conditioner (UPQC). Along with providing active (AP) to the utility grid, Wind-PV-UPQC improves PQ indicators, for example, voltage drops/surges, harmonics grid voltages, PF. Since depends on dual compensation scheme, parallel converter works as sinusoidal...

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...

This paper presents a new Unified PowerQuality Conditioning System (MCUPQC),capable of simultaneous compensation for voltage and current in multi-bus/multi-feeder systems. By using one shunt Voltage-Source Converter(VSC) and two or more series VSCs the configuration is made. The system can be applied to adjacent feeders to compensate for supplyvoltage and load current imperfections on the main ...

Performance degradation is, in general, regarded as a power quality problem. One solution to recover grid performance is through the application of unified conditioner (UPQC). Although these devices are multi-input/multi-output (MIMO) systems, most common control strategies consist two decoupled controllers, which neglect coupling effects and add uncertainty system. For this reason, paper propo...
