This paper presents the performance improvement of dynamic voltage restorer (DVR) by vector control (V-control ),  which improves transient performance  of  DVR.    Both current and voltage controllers are incorporated by V-Control, with an inner current control loop and outer voltage control loop. The loop gains are determined   according to the system analysis, carried out on closed   loop system.  Also a review of the reported control techniques that have been implemented to control the injected voltage by DVR is presented. Simulation results have proved that the proposed algorithm is able to improve transient response of DVR.
