CONTROL OF REDUCED RATING DVR WITH A BATTERY ENRGY STORAGE SYSTEM

Power quality problems become a major anxiety of industries due to enormous loss in terms of time and money. The power quality consists of a large number of disturbances such as voltage sags, swells, harmonics, notch, flicker, etc. There are the various methods to alleviate the power quality problems, but the FACTS devices are the most excellent solution to alleviate this problem. One of the most powerful FACTS devices is the DVR to alleviate the voltage sag and swell. The performance of any custom power device depends very much upon the control algorithm used for the reference current estimation and gating pulse generation scheme. The operation of a DVR has been demonstrated with a new control technique using various voltage injection schemes.
