Series-Connected Grid-Following and Grid-Forming Hybrid Control Strategy for VSC-HVDC Converters to Enhance Transient Voltage Stability in Receiving-End Power Grids
With an increase in the High-Voltage Direct Current (HVDC) infeed, the strength of the receiving-end AC grid decreases, leading to transient voltage instability. Voltage source converter (VSC)-HVDC stations have a large unit capacity and high controllability, offering great potential for voltage support of the receivin...
