Abstract

Point-to-point VSC-HVDC Wind power plant (WPP)
links connected offshore by AC cables can be called an AC
integrated VSC-HVDC scheme or virtual multi-terminal DC
(MTDC) grid. Since, the AC integrated VSC-HVDC scheme
forms an offshore AC grid, parallel operation of offshore VSC-
HVDC converters is required. This paper compares three
offshore converter control topologies: (i) feedforward control of
AC voltage and frequency, (ii) feedback control of AC voltage,
and (iii) feedback control of AC voltage and frequency with an
inner current loop. The performance of power and current
based droops has been assessed for the parallel offshore
converters. Simulations carried out in DIgSILENT Power
Factory are presented to illustrate the effect of these offshore
converter control strategies on the dynamics of the AC system
following the offshore grid disturbances.
