Super conducting magnetic energy storage based DVR

Abstract

Superconducting magnetic energy storage (SMES) technology has been progressed actively in recent years. SMES technology has the potential to bring real power storage characteristic to protect consumers from the grid voltage fluctuations. This paper analyses the operation principle of the SMES based DVR and its design is based on simple PI control method to compensate voltage sags. Using MATLAB SIMULINK, the models of the SMES based DVR is established, and the simulation tests are performed to evaluate the system performance.
