Monitoring area screening of AC system to improve embedded VSC‐HVDC operation efficiency

Abstract With the increasing number of embedded high‐voltage DC (HVDC) projects in AC systems, there is growing research interest in controlling the operating point of the HVDC in real time. This real‐time operation system requires the AC system information to be continuously updated, which involves...
