GMD Integrated Tool (GeoIT): An Integrated Tool for Performing Geomagnetic Disturbance Vulnerability Assessment Studies

Abstract

The impact of geomagnetic disturbances (GMDs) continues to be a significant concern for the North American bulk power system (BPS). In order to assess potential system vulnerabilities and evaluate appropriate mitigation measures, several planning studies must be performed in conjunction, as outlined in the NERC Reliability GMD Vulnerability Assessment Requirement (TPL-007). Presently these studies are conducted across multiple software platforms which requires multiple databases and user intervention. This paper presents a tool that integrates the TPL-007 studies across these multiple platforms, enhancing the accuracy and efficiency of the GMD vulnerability assessment.
