Standby Mode Operation of Series Type SMES for Voltage Sag Compensation

In this paper, the novel standby mode operation of series type SMES (Superconducting Magnetic Energy Storage) for voltage sag compensation is presented. In the proposed control scheme for standby mode, the power losses are minimized and voltage drop is mitigated. The series type SMES is bypassed during the normal weather. During the adverse weather, the series type SMES can compensate voltage sags instantaneously. Simulations of standby mode operation and voltage sag compensation demonstrated the validation of the proposed control scheme.
