Compensation of voltage flicker using Unified Power Quality Conditioner (UPQC)
2014 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2014Voltage flicker, which is a repetitive voltage magnitude change of low frequency, is one of the power quality problems. The problem is aggravated with the use of non-linear load. The paper presents the use of a Unified Power Quality Conditioner (UPQC) as a solution to voltage flicker. A simple control technique is proposed to control UPQC.

A unified power quality conditioner (UPQC) for simultaneous voltage and current compensation
Electric Power Systems Research, 2001Abstract The paper discusses the topology and control of a unified power quality conditioner (UPQC) that can be used simultaneously in voltage or current control mode in a power distribution system. In the voltage control mode, the UPQC can force the voltage of a distribution bus to be balanced sinusoids.

A new control scheme for unified power quality conditioner (UPQC)
2011 3rd International Conference on Electronics Computer Technology, 2011This paper presents a solution to the control of a unified power quality (PQ) conditioner (UPQC) for Power Quality improvement in power distribution systems. The problem formulation allows not only harmonic compensation but also voltage sags/swells, load demand changes, and power factor correction to be tackled in a unified framework.

A New Control Strategy for Unified Power Quality Conditioner (UPQC) In Distribution Systems
2006 International Conference on Power System Technology, 2006This paper presents a novel and easy to implement control strategy for unified power quality conditioner (UPQC). The control strategy of parallel active filter (PAF) is based on fourier transform theory, while the control circuit of series active filter (SAF) is based on positive sequence detection theory. Operating of PAF using this method compensates
