Investigations on the Effects of DC Voltage Control on Inertia Provision in HVDC Converter Stations
This paper first demonstrates that if there is only one station in charge of DC voltage control, this station cannot provide any real inertia power during frequency events but instead adversely produces a small equivalent negative inertia.
