Coordinated reactive power control for hybrid cascaded high‐voltage direct‐current links in weak AC grids

IET Generation, Transmission & Distribution
The hybrid cascaded high‐voltage direct‐current (HC‐HVDC) links are recently introduced for ultra‐high voltage bulky power transmissions. However, as wind power becomes more prevalent, the grid is gradually weakened and will face voltage stability issues.
