Abstract

The present disclosure relates to method and a controller for controlling a wind power generation system. The system is connected to a grid at a point of connection, and is devised to feed reactive power to the grid in order to improve grid stability. A Q-V characteristic is determined for the grid at the point of connection as well as a nose point for the Q-V characteristic. A minimum reactive current, lQmm, which is safe from the nose point, is determined, and the feeding of reactive power is controlled such that the reactive current is kept higher than the minimum reactive current. In this way it is made sure that the reactive current does not make the Q-V characteristic reverse, and thereby the stability of the system is improved.
