Optimization of voltage sag/swell using dynamic voltage restorer (DVR)
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016The most interesting issue for electrical engineers is power quality/power quality improvement in modern era. Power quality is the most noticeable trouble for electrical engineering students. This problem occurs due to occurrence of substandard voltage, may be substandard current, and of frequency which contain harmonics which may damage to power ...

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

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.

Compensation of voltage sags and swells by using Dynamic Voltage Restorer (DVR)
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016The most important aspect for electrical engineering is power quality in recent year. Power quality problem is an event of abnormal voltage, current or frequency. Utility distribution networks experience from various types of disturbances. The major problems dealt here are the voltage sags/swells.

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.

A Dynamic Voltage Restorer (DVR) based interface scheme for microgrids
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014This paper deals with the issues related to the interconnection between the microgrid and main network. The Dynamic Voltage Restorer (DVR) is proposed as an interface between the main network and microgrid in order to improve reliability and limit fault currents. The performance of DVR is demonstrated during fault conditions in two different locations,

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
