In order to accommodate more wind power by dispatching electric vehicle（EV） charging and discharging

we put forward a unit commitment strategy considering cooperated dispatch of EVs based on scheduling capacity and wind power generation. According to the scheduling ability

the load of EV is divided into disordered charging load

adjustable charging load

and adjustable charge-discharge load. By using the vehicle driving behavior model to simulate the travel rule of EV

the model of the EV condition matrix and the electric vehicle’s controllable charge-and-discharge capacity can be set up. The EV charge-discharge load is used as a variable in the unit commitment. A unit commitment model is proposed for optimal coordination of wind power generation and charging load of EV. From the aspect of economic benefit

we analyze the unit cost

wind curtailment

the operator benefit

user charge cost in different combination of EVs when the EVs charge and discharge adopt the time-of-use prices. Cases study shows that

by the proposed UC model

the wind abandonment can be decreased as well as the cost of Vehicle-to-Grid（V2 G）.
