Abstract Voltage sag is an primary energy satisfactory situation for which the dynamic voltage restorer (DVR) is known as an mighty gadget to mitigate them. The Dynamic Voltage Restorer (DVR) is fast, bendy and effective option to voltage sag hindrance. SMES science has the abilities to carry actual vigor storage attribute to look after consumers from the grid voltage fluctuations. The DVR can restoration the load voltage within few milliseconds. A few configurations and manipulate ways are proposed for the DVR. To clear up this trouble, super conducting magnetic power storage (SMES) situated dynamic voltage restorer (DVR) is introduced to preserve patrons from the grid voltage fluctuations. Because of its excessive vigor density and fast response, it's selected as the vigor storage unit to beef up the compensation ability of DVR. The paper concentrates on efficiency advantages of adding power storage to vigor digital compensators for utility purposes. Simulation results have been presented to illustrate and realize the performances of DVR below voltage sags stipulations. The results got by simulation using MATLAB established the effectiveness of this gadget in compensating voltage sags with very rapid response (relative to voltage sag time).
