Compensation of Distribution System Voltage Using Dynamic Voltage Restorer (DVR)
IEEE Power Engineering Review, 2002A dynamic voltage restorer (DVR) is a power electronic controller that can protect sensitive loads from disturbances in the supply system. This device can tightly regulate the voltage at the load terminal against imbalance or harmonic in the source side.

Review of voltage compensation methods in dynamic voltage restorer (DVR)
2012 IEEE Power and Energy Society General Meeting, 2012Voltage sag is a common and undesirable power quality phenomenon in the distribution systems which puts sensitive loads under the risk. An effective solution to mitigate this phenomenon is to use dynamic voltage restorers and consequently, protect sensitive loads. Four basics compensation methods were proposed in the research community to eliminate the

Software phase-locked loop applied to dynamic voltage restorer (DVR)
2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002In this paper, the analytical and practical design issues of a software phase-locked loop (SPLL) for DVR are presented. A SPLL model that uses a lag/lead loop controller, is derived in order to analyse the system performance and filtering characteristic by the use of bode diagrams and root-locus methods. In DVR applications, parameters of the design of

A supervisory hierarchical fuzzy controller for dynamic voltage restorer (DVR)
2015 23rd Iranian Conference on Electrical Engineering, 2015Dynamic voltage restorer (DVR) is a static Var compensator that plays an important role in voltage sag/swell compensation, especially during faults. This paper proposes a novel fuzzy logic based control structure to improve DVR performance. The proposed structure consists of two layers, namely, the lower or main layer and the upper or supervisor layer.

The Role Of Dynamic Voltage Restorer (DVR) in improving power quality
2016 2nd International Conference on Advances in Electrical, Electronics, Information, Communication and Bio-Informatics (AEEICB), 2016One of the control strategies of DVR (Dynamic Voltage Restorer) is minimum energy control strategy which is explained in this paper. The main duty of power system is to supply their customers a uninterruptable power supply at all the times, but in practice it is not happening.
