This paper presents a comprehensive study that includes the sizing and power flow by series parallel inverters in distributed generation system (DGs) integrates of hybrid wind photovoltaic with unified quality conditioner (UPQC). In addition to supplying active utility grid, functions as UPQC, compensating reactive suppressing harmonic load currents. Additionally, is supplied harmonic-free, bal...

This project presents a power quality improvement of unified power quality conditioner (UPQC) to compensate current and voltage quality problems of sensitive loads. The UPQC consists of the series and shunt converter having a common dc link. The series converter mitigates voltage sag from the supply side and shunt converter eliminates current harmonics from the nonlimear load side. The develope...

In recent years, there is tremendous growth in the use of power electronic devices in every sphere but in nonlinear loads, it has problem of drawing the two important limitations; draws the non-sinusoidal current and reactive power from source which in turn effects the power quality. This paper presents the performance evaluation of unified power quality conditioner (UPQC) for current and volta...

Abstract – This paper describes a novel structure for single phase Unified Power Quality Conditioner-Distributed Generation (UPQC-DG) with direct grid connected DC-AC converter for low DC output DG systems which can be used not only for compensation of power quality problems but also for supplying of load power partly. This converter has been composed of one full-bridge inverter, one three wind...

This paper presents a multi-objective control strategy for power quality issues. With increasing applications of nonlinear and semi-conductor devices in distribution systems and industries, power-quality (PQ) problems, such as harmonics, neutral current elimination, voltage sag, voltage swell reactive power has become an unavoidable issue. Due to the changing trends and restructuring of power s...
