Abstract:
In this paper a novel Adaptive Droop Control (ADC)
strategy is implemented for Grid Side Voltage Source Converters
(GS-VSC) of Multi-terminal HVDC (MTDC) grids. The proposed
method regulated the dc voltage by sharing appropriate power
between the converter stations. During any converter outage
or power imbalances, the proposed ADC ensures that the
rest of converters are not burdened or operated beyond the
converter ratings. The proposed ADC operate effectively without
any communication between the converters. The evaluation of
proposed control ADC is done by creating contingencies like
converter outage, fault on the AC and DC side of the grid. The
proposed method shows improved performance as compared with
the conventional Voltage Droop Control (VDC). The CIGRE B4
working group DC grid benchmark test system is used to show
the outperform of proposed ADC scheme in comparison with
conventional VDC
