Investigation of Voltage Sag and Swell Problems using DVR and Fuzzy Logic

Mitigation of voltage sag/swell using Dynamic voltage restorer (DVR)

The most noticeable topic for electrical engineering is power quality in recent year. Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency. Utility distribution networks, sensitive industrial load and critical commercial operation suffer from various types of outages and service interruption can cost significant financial losses. One of the major prob...
