The applications of FACTS devices have become popular in the last few
decades. There are many types of FACTS devices that are currently used in power
systems to improve system stability, power quality and the overall reliability of the
power systems. Since the involvement of renewable energies based power plants such
as wind and PV, problems related to power system stability and quality has become
even more complex, therefore the deployment of FACTS devices has become a
challenging task. In this chapter, a Superconducting Magnetic Energy Storage (SMES)
Unit is applied to improve the performance of Doubly Fed Induction Generator (DFIG)
based wind turbine during various disturbances such as voltage sag, short circuit faults
and load variation, including problems related to internal faults within the DFIG
converters.
Keywords: Superconducting Magnetic Energy Storage, Wind Energy conversion
system, Fault ride through, Active and reactive power modulation.
