Electrically meaningful power system test case diagrams (Texas A&M Electric Grid Test Cases)

These images show simple test system diagrams for three of the test power systems in the Texas A&M "Electric Grid Test Cases" collection (see https://electricgrids.engr.tamu.edu/ and A.B. Birchfield, T. Xu, K.M. Gegner, K.S. Shetye, T.J. Overbye, "Grid
Structural Characteristics as Validation Criteria for Synthetic
Networks," to appear IEEE Transactions Power Systems)The three networks visualized here are "Illinois 200-Bus System: ACTIVSg200", "SouthCarolina 500-Bus System: ACTIVSg500" and "Texas 2000-Bus System: ACTIVSg2k" These network diagrams were created by applying the techniques described in:P. Cuffe; A. Keane, "Visualizing the Electrical Structure of Power Systems," in IEEE Systems Journal, 2015The "Power Transfer" distance was use to create each diagram (see ibid. Section II. 3) As such, the diagrams are electrically meaningful: loosely speaking, buses drawn in close proximity should be able to transact power with each other with ease.Buses have been labelled as space permits, starting with the highest voltage buses first.

本组图像展示了德克萨斯A&M大学“电网测试案例”集中三种测试电网的简易测试系统图示（详见https://electricgrids.engr.tamu.edu/以及A.B. Birchfield, T. Xu, K.M. Gegner, K.S. Shetye, T.J. Overbye, 《合成网络验证标准：电网结构特性》，即将发表于IEEE Transactions Power Systems）。此处可视化的三个电网分别为：“伊利诺伊州200节点电网：ACTIVSg200”、“南卡罗来纳州500节点电网：ACTIVSg500”以及“德克萨斯州2000节点电网：ACTIVSg2k”。这些网络图是通过应用P. Cuffe和A. Keane在IEEE Systems Journal 2015年发表的《可视化电网的电气结构》一文中描述的技术所创建的。每个图示均采用了“功率传输”距离进行绘制（参见同上第II.3节）。因此，这些图具有电气意义：简言之，绘制在邻近位置的母线应当能够轻松地进行电力交易。在空间允许的情况下，已对母线进行标注，首先从电压最高的母线开始。
