Voltage sags are one of the main problems
Voltage sags are one of the main problems in transmission
and distribution grids with high penetration of distributed
generation. This paper proposes a voltage support control scheme
for grid-connected power sources under voltage sags. The control
is based on the injection of reactive current with a variable ratio between
positive and negative sequences. The controller determines,
also, the amount of reactive power needed to restore the dropped
voltage magnitudes to new reference values confined within the
continuous operation limits required in grid codes. These reference
values are chosen in order to guarantee low current injection
when fulfilling the voltage support objective. Selected experimental
results are reported in order to validate the effectiveness of the
proposed control.
