The consumption problem is the bottleneck of utilizing large-scale of wind power,and dispatch decisions are the cores to absorb wind power.Aiming at the characteristics of randomness and volatility of wind power,a reserve requirement model of integrated wind power was established based on the relationship among the probability distribution of wind power forecasting error and power fluctuation and reserve requirement variations.The uncertainty of wind power output was quantified.In order to solve the consumption problem of wind power,in dispatch decisions,wind power was considered as sources which can actively participate in the dispatch and the reserve-coordinated-optimization dispatch model of the wind power dynamic acceptance interval was constructed.The uncertainty of wind power and makes reasonable integrated wind power capacity interval schedule and unit commitment schedule were considered,which ensures the security of power system while meeting the economy of system operation.The modified IEEE6 bus and IEEE118 bus systems were used to verify the accuracy and effectiveness of the proposed model. The results provided a method to absorb wind power reasonably and in a maximum degree in power system with large-scale of wind power.
