A STATCOM with Supercapacitors for Low-Voltage Ride-Through in Fixed-Speed Wind Turbines [PDF]
Energies, 2014 Fixed-speed wind generator (FSWG) technology has an important presence in countries where wind energy started to be developed more than a decade ago. This type of technology cannot be directly adapted to the grid codes, for example those requirements related to the immunity level under voltage dips.
