摘要:

针对电动汽车的不同数量和风电出力的不确定性对电网调度的影响,建立含风电出力不确定性和电动汽车的日前调度区间优化模型。首先,将风电出力的不确定性利用区间数进行表示;然后考虑电动汽车不同数量及运行约束,建立日前调度区间优化模型;接着,将日前调度区间优化模型转换为两个子模型进行求解;最后,利用10机组系统对所提模型进行验证分析。通过算例分析验证了所提模型的准确性与经济性。

Abstract:

To address the impact of different numbers of electric vehicles (EVs) and uncertainty of wind power output on power grid dispatching,the day-ahead dispatching interval optimization model with the uncertainty of wind power output and EVs is established.First,the uncertainty of wind power output is represented by the interval number.The interval optimization model of day-ahead dispatching is established by considering the different numbers and operation constraints of EVs.Then,the interval optimization model of day-ahead dispatching is converted into two sub-models for solving.Finally,the proposed model is tested and analyzed by using the 10-unit system.The accuracy and economy of the proposed model are verified through the analysis of arithmetic cases.

Key words: electric vehicles, day-ahead model, optimization, interval
