Superconducting Magnetic Energy Storage Unit for Damping Enhancement of a Wind Farm Generation System

E. Salih, S. Lachowicz, O. Bass, and D. Habibi
Abstract—A superconducting magnetic energy storage (SMES)systemcontainsa high inducting coil and combines with power conversion system can act as a constant source of direct current. SMES unit connected to a power system is able to absorb and store both active and reactive power from this system and to inject these powers into the powersystem in the demand periods. These injected powers are controlled by changing both the duty cycle of the dc-dc chopper switches and its operation modes. This paperpresents an efficient design based on anSMES unit controlled by the artificial neural network (ANN) to improve transient stability by regulating the dc link voltage and to damp the voltage and frequency fluctuations that are always associated withwind power generator. The authors propose interfacing theSMES between wind power farm and the power grid connected throughthe DC Link capacitor to rapidly stabilize the voltage and frequency fluctuations in the power system.The system behavior is tested with three different events for both voltage and frequency fluctuations of wind power generationwith and without applying the SMES unit. The results show that both voltage and frequency stabilities are significantly increased when the SMES unit is applied inthese three events.

Index Terms—Power stability, superconducting magnetic energy storage (SMES), transient, wind power generation.
