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&amp;M "<i>Electric Grid Test Cases</i>" 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)<br><br>The three networks visualized here are "<i>Illinois 200-Bus System: ACTIVSg200</i>", "<i>SouthCarolina 500-Bus System: ACTIVSg500</i>" and "<i>Texas 2000-Bus System: ACTIVSg2k</i>" <br><br>These network diagrams were created by applying the techniques described in:<br>P. Cuffe; A. Keane, "Visualizing the Electrical Structure of Power Systems," in IEEE Systems Journal, 2015<br><br>The "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.<br><br>Buses have been labelled as space permits, starting with the highest voltage buses first.<br><br>
