Adapting the Grid to the Customer of the Future

Workshop 2: GMD

Topic: Geomagnetic Disturbances
Date: 2018 October 15, Monday
Time: 8:00 am to 12:00 noon
Coordinator: Colin Clark of AltaLink

Space weather interactions with the earth can result in a number of impacts on the electrical network and associated equipment. The often referred to Hydro Quebec geomagnetic storm in 1989 was a catalyst for further research. The research and studies today depict a stark contrast to industry perceptions less than a decade ago.
This workshop will cover recent research into how Geomagnetic Disturbances interact with the earth and the corresponding effects on the power system.   A utilities approach to monitoring GMD as well as the results from large area system study will be presented.  
NERC Standard TPL-007 defines the requirements for how utilities should address the impacts of space weather on the power grid. The published benchmark event and scaling factors are a subject of debate. In 2018 NERC recognized that as GMD research and earth modelling evolves, specific Canadian revisions may be required to incorporate alternative benchmark GMD events in Canada appropriate for the geographical region. While the specific NERC TPL-007 standard is not a workshop topic, this recent work highlights the subject relevancy in Canada.

There are three presentations in this GMD Workshop:
