Criterion for the electrical resonance stability of offshore wind power plants connected through HVDC links [PDF]

open access: yes, 2017
Electrical resonances may compromise the stability of HVDC-connected Offshore Wind Power Plants (OWPPs). In particular, an offshore HVDC converter can reduce the damping of an OWPP at low frequency series resonances, leading to system instability.
