Earth Resistivity Model for GIC Calculations

PowerWorld Simulator GIC can automatically incorporate scaling factors for geomagnetic latitude and earth resistivity according to NERC TPL-007-2 – Transmission System Planned Performance for Geomagnetic Disturbance Events (October 2017). The earth resistivity models must be loaded from an auxiliary file. Those described in TPL-007-2, Table 3: Geoelectric Field Scaling Factors, are available here (revised January 31, 2018). These include scaling factors for both the Benchmark Event and the Supplemental Event.
