考虑电动汽车充电与常规负荷时空相关性的配电网可开放容量评估 [PDF]
全球能源互联网传统配电网可开放容量评估未充分考虑电动汽车充电负荷与常规负荷的时空相关性，导致评估过于保守，难以指导配电网实际规划。为此，提出了一种考虑电动汽车（EV） 充电负荷与常规负荷时空相关性的配电网可开放容量评估方法。首先通过考虑EV充电负荷与常规负荷的时空相关性选取负荷典型日；接着构建可开放容量评估鲁棒随机优化模型，并采用KKT条件将其转化成单层模型；最后，在改进IEEE 33节点系统上仿真，验证了所提方法的优点。结果表明，相较于传统方法，所提方法基于对负荷相关性的量化，可获得更准确合理的配电网可开放容量 ...

全球能源互联网, 2018 采用非线性导线模型，结合重冰区特高压输电线路实际情况进行计算机建模，应用有限元分析，计算档数、档距、覆冰量、脱冰比、高差、风速等因素与导线脱冰跳跃的关系。同时定性分析了导线脱冰跳跃的影响因素，对工程设计提出建议。计算结果表明，在耐张段内档数不超过5档时，脱冰跳跃高度随档数增加而增大；在档距小于1000 m时，档距越大，脱冰跳跃越严重；覆冰量越多，脱冰跳跃越严重；高差越大，垂直脱冰跳跃高度越小；风速越大，脱冰跳跃水平位移值越大。通过对计算结果的分析，对塔头设计时导（地）线层间距、水平偏移值的确定给予建议。

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT
Astronomische Nachrichten, EarlyView.ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).
