To comply with the national standard of wind power integration，the fluctuations of wind power must be mitigated.An optimization control method of wind/storage hybrid system is proposed，which can suppress the wind power ramp rate and meet the ramp rate requirement in the standard.A mathematical expression for wind power ramp rate is presented as per the definition of active power change in the national standard.Based on the ultra-short-term/short-term wind power prediction，a rolling optimization model which adopts wind curtailment control and storage control is established to maximize the total profit of wind/storage hybrid system.The model is solved by genetic algorithm.A test case is developed based on the parameters of a practical wind plant to show its effectiveness.
