Abstract: A Dynamic Voltage Restorer (DVR) is connected in series with the network.The main function of a DVR is the protection of sensitive loads from influence of the voltage fluctuation, especially voltage sag.This paper deals with the main identification methods, combines the characteristics of the loads to have a general compare.

Keywords: Dynamic voltage restorer; Voltage sags; Symmetrical component; Kalman filtering
