Description: Voltage sags and swells in the medium and low voltage distribution grid are considered to be the most frequent type of power quality problems based on recent power quality studies. Their impact on sensitive loads is severe.  The impact ranges from load disruptions to substantial economic losses up to millions of dollars. Different solutions have been developed to protect sensitive loads against such disturbances but the DVR is considered to be the most efficient and effective solution. Its appeal includes lower cost, smaller size and its dynamic response to the disturbance. This paper described DVR principles  and  voltage  restoration  methods  for  balanced  and/or  unbalanced  voltage sags  and  swells  in  a  distribution  system.  Simulation results were presented to illustrate and understand the performances of DVR under voltage sags/swells conditions.
