Investigation of the impact of embedded VSC-HVDC active and reactive power control on power system stability

Control and stability analysis of VSC-HVDC based transmission system connected to offshore wind farm

“…Therefore, HVDC transmission line is considered a key technology for this purpose. The main feature of transmission system based on VSC-HVDC is its ability for independent control of active and reactive power flow in each of the AC grids as addressed in [8][9][10][11][12].…”

System congestion criteria for interconnection of WPP through VSC‐HVDC

“…This kind of connection to the AC transmission power system has two impacts, by one side the injected active power from the WPP can congest the AC network around the point of connection. By the other hand, VSC has the ability to control active power and reactive power independently [6], which can be used to increase the transport capacity of the system as a Static Synchronous Compensator (STATCOM) does [7]. On the other hand, the VSC technology changes the direction of the current instead of the voltage that avoids an increased electric field after a voltage reversal within e.g.…”
