Abstract
A wind turbine comprises a power converter connected between a generator in the wind turbine and a power grid. The power converter comprises a direct-current (DC) link and is adapted to supply a current to the power grid. A detection unit is adapted to detect a voltage of the power grid. When the detection unit detects that there is a voltage drop in the power grid, a voltage at the DC link is decreased thereby increasing the current supplied to the power grid.
