Novel cascading scheme of VSC‐HVDC with DC voltage synchronisation control for system frequency support

Abstract This paper introduces a novel cascading frequency regulation scheme (CFRS) for VSC‐HVDC to provide strong support for the connected weak AC grid without phase‐locked loop and remote‐communication considering the cost‐effective property. The proposed CFRS utilises a DC voltage synchronisatio...
