The main purpose of this series of papers is to provide methodology and best business practices to assess the risk posed by geomagnetic disturbances. This paper addresses the methodology used by Dominion Virginia Power to model geomagnetically induced currents. An extreme 100-year geoelectric-field scenario is utilized as a baseline. The impact of topology changes in a large 497-bus system is investigated. Subsequent papers-Parts II and III-will address transformer vulnerability and system voltage stability, respectively.
