Abstract: This paper describes the super conducting magnetic energy storage SMES based dynamic voltage restorer to protect consumers from the grid voltage fluctuations. DVR can be effectively provide a fine solution to power quality related concerns. As per the PQ issues sag is the mostly happen problem. By the Superconducting magnetic energy storage (SMES) technology based DVR the sag is mitigated a0nd real power is restored and thus wastage is overcome, providing protection to consumers from grid voltage fluctuations. . Due to the characteristic of high energy density and quick response, a superconducting magnet is selected as the energy storage unit to improve the compensation capability of DVR. This paper analyses the operation principle of the SMES based DVR, and designs the DVR output voltage control method using MATLAB SIMULINK, the models of the SMES based DVR is established, and the simulation tests are performed to evaluate the system performance.
