Reactive power control in hvdc
Webreactive power capability verification. • VSC HVDC: VSC HVDC is different than LCC HVDC in that it has independent control of active and reactive power because of the independent voltage source within the converters. Therefore, these elements are able to operate in automatic voltage control, controlling their terminal voltage (or Web1.3.1 PQ Control. The main objective of PQ control is to keep the microsource’s active power and reactive power constant when the frequency and voltage deviation stay within …
