A real-time wind power control method is proposed to accommodate the severe fluctuation of wind power

which can be used in power systems with high wind power penetration. The maximum allowable wind power generation is estimated online according to the automatic generation control (AGC) downward spinning reserve and the tie-line power deviation. Considering the different priorities for wind farms and the transmission security constraints

different control strategies

such as corrective control to eliminate the transmission congestion

optimal dispatch considering the trade-off between minimum curtailment of wind power and the fairness among wind farms

are integrated in the proposed method. The numerical simulation on the test system and the results of field operation in a provincial power grid show that the method is efficient and practical.
