Abstract: In a decentralized manner, providing Frequency Support (FS) to the AC integrated Multi-terminal DC (AC-MTDC) grids is requisite from most of the Transmission System Operators (TSO's). Extracting this support from the Wind Farms (WFs) through the DC grid is engrossing researchers. In this paper, unlikely, P V 2 is proposed instead of P f droop control for Wind Farm Voltage Source Converters (WFVSCs) for effective FS. This support is achieved while operating the WFs in a derated mode of operation. Besides, this approach also enhances the DC-voltage support to the MTDC grid. In addition, wind variation is also considered to show the impact of this variation on the Frequency and DC-voltage Support (FDS). Further, the proposed approach is validated by considering two area power systems integrated into the five terminal mesh type DC grid with three various schemes simulated in PSCAD/EMTDC software.
