    • The present invention relates to a method and system for controlling a wind farm when a ramp up or ramp down rate of the wind farm does not satisfy a grid-code or corresponding criteria due to an abrupt change in wind speed. The method and system for controlling a wind farm includes the steps of measuring speed and direction of wind performed outside the wind farm, sequentially controlling wind turbines if the wind speed abruptly changes considering a time for the wind to arrive at the wind turbines, determining the number of wind turbines to be controlled simultaneously so that the wind farm may satisfy the grid-code at this point, grouping the wind turbines, determining a control sequence and a control time of each group, and adjusting a control end time if stopping times of adjacent groups are overlapped when the wind turbines are stopped.
