How to tune "DC & AC voltage control override" (VSC-HVDC demo)

Hello everybody,

Does anybody know how to tune the controllers "DC Voltage Control Override" and "AC Voltage Control Override"? They are both included in the demo about VSC-HVDC link.

Thanks, Ana

Do you want them tuned for Rock'N'Roll, Blues, or Hip-Hop ?

In the documentation "VSC-Based HVDC Link", we can read:

_[...] The AC Voltage control override block, based on two PI regulators, will override the reactive power regulator to maintain the PCC AC voltage within a secure range, especially in steady-state.

[...] The DC Voltage control override block, based on two PI regulators, will override the active power regulator to maintain the DC voltage within a secure range, especially during a perturbation in the AC system of the station controlling the DC voltage._

You can adjust the PI regulators and their range of operation in the VSC Controller mask.

but sir how you can make a relation between PI and DC Voltage control override block?
