Fast Harmonic compensation in hybrid HVDC offshore system

open access: yesJournal of Physics: Conference Series, 2022
Hybrid HVDC systems have been proposed as an alternative for nominal VSC-Based HVDC for offshore applications. Hybrid HVDC systems consist of an offshore power station composed of the connection of high-power diode rectifiers in series with a fractional power VSC-HVDC.
