Abstract
A method performed by a DC voltage controller for a HVDC converter, including generating a synchronous angular speed and synchronous phase angle based on a DC voltage error signal; determining an AC grid phase angle from a combination signal, wherein the combination signal is based on an AC grid signal and a function of the synchronous angular speed; generating, for the HVDC converter, a phase angle demand, wherein the phase angle demand is based on the AC grid phase angle and the synchronous phase angle.
