Balanced voltage sag & swell compensation by using dynamic voltage restorer
2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016To mitigate voltage disturbances in low voltage distribution system dynamic voltage restorer (DVR) with energy storage device is used in this paper. DVR is installed between supply and load which will inject voltage and active power to the distribution system during balanced voltage sag and swell disturbances.

Application of Dynamic Voltage Restorer in microgrid for voltage sag/swell mitigation
2015 IEEE Power, Communication and Information Technology Conference (PCITC), 2015Microgrids are becoming increasingly attractive to consumers as it allows utilization of freely available renewable energy sources. They are usually installed at consumer's sites i.e the distribution end. Due to high penetration of distributed generation units with different types of loads, microgrids can cause power quality and power control issues ...

A proposed Transformer-less Dynamic Voltage Restorer to Voltage Sag/swell Mitigation
2019 IEEE Conference on Power Electronics and Renewable Energy (CPERE), 2019Power quality can be improved by reducing the voltage disturbances. The dynamic voltage restorer (DVR) increases the power quality by compensating the voltage disturbance. This paper presents a transformer-less DVR that can recover the voltage disturbances to that the same magnitude and phase angle before disturbance occurs, by using dq0 measurement ...

Dynamic Control Strategy in Medium Voltage DVR for Mitigating Voltage Sags/Swells
2006 International Conference on Power System Technology, 2006This paper presents control algorithm for dynamic voltage restorer (DVR) to improve voltage quality problems such as voltage sags/swells in distribution systems. When voltage sags/swells occur, possibly, due to faults and some load switching, DVR has to detect the problem and inject appropriate voltage component as soon as possible.

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.

Mitigation of Voltage Swell by Switched Autotransformer with Random Hysteresis Voltage Control
2011 Asia-Pacific Power and Energy Engineering Conference, 2011This paper presents a voltage swell compensator based on a switched autotransformer by random hysteresis voltage control. The advantage of this compensator is that it uses only one controlled switch per phase with no energy storages. Also the control scheme purposed here distributes the harmonic spectrum of the load voltage and reduces its total ...

Modified series compensation for voltage sag / swell mitigation
2014 IEEE 6th India International Conference on Power Electronics (IICPE), 2014A voltage source inverter (VSI) is employed to implement a variable frequency drive (VFD) for obtaining desired speed-torque characteristics of an AC motor which is normally fed by a diode rectifier at the front end. These uncontrolled converters inject excessive harmonic currents in to AC mains resulting in detoriated power quality in terms of AC ...
