摘要(Abstract)：

风电大规模并网使得输电网网架规划所考虑的不确定性利益日益增加,灵活性规划难度加大。传统的规划后校验方法难以精确地量化不确定性指标,易造成规划方案的线路冗余,增加投资成本。针对风电出力的随机性,构建并分析了嵌入先校验失负荷概率(loss of load probability,LOLP)约束的网架规划模型,在对模型凸松弛的基础上,应用超分位数理论对LOLP约束实现确定性转化,随后对原问题和松弛后的问题迭代求解来减少估计误差。最后,以IEEE 30和IEEE 118节点系统验证了所提模型和算法的有效性,并分析了所提模型计算成本及风电场景选取对规划方案的影响。

关键词(KeyWords)： 缓冲故障率;网架规划;失负荷概率约束;确定性转化
