Abstract
A method performed by a DC voltage controller for a HVDC converter, including generating a synchronous phase angle from a DC voltage error, wherein the DC voltage error is generated from a measured DC voltage and a demanded DC voltage; generating an AC grid phase angle from an AC grid signal; generating a DC power compensation function based at least in part on the measured DC voltage; and generating, for the HVDC converter, a phase angle demand based on at least one of: the synchronous phase angle, the AC grid phase angle, and the DC power compensation function.
