Controlling operation of a wind turbine coupled to a power grid is disclosed. The power grid is monitored in order to determine whether or not there is a match between a demand for energy defined by power consumers connected to the power grid and supply of energy from power producers connected to the power grid. For instance, the price of energy may be monitored. In the case that the supply of energy from power producers exceeds the demand for energy, and a deficiency between the demand for energy and the supply of energy exceeds a first threshold value, the energy flow through the generator is reversed, thereby causing the generator to consume power received from the power grid. Thereby the deficiency can be reduced and the power grid can be stabilised.
