摘要

提出了一种基于限电的风电大规模并网后区域间总输电能力评估方法。首先,基于Copula函数建立了考虑风电功率相关性的数学模型。然后逐个求解蒙特卡罗生成的每个样本的TTC,从而筛选出有效样本。在此基础上,建立了基于风力输出约束最小化弃风量的区域间TTC二级评估模型,并在PJM-5测试系统上验证了该方法的有效性。

Total Transfer Capacity Calculation with Large Scale Wind Power Considering Power Curtailment
This paper presents a power curtailment based method to assess inter-regional total transfer capability (TTC) after large-scale integration of wind power into grids. Firstly, a mathematical model considering wind power correlation is established based on Copula function. Then TTC of each sample generated by Monte Carlo is solved one by one so as to screen valid samples. Moreover, a TTC bi-level assessment model is developed, in which wind power curtailment is minimized by wind output constraint, in order to improve the inter-regional TTC The effectiveness of the proposed method is verified by experiments on test system PJM-5.
