Space Weather and Compliance with NERC Standard TPL-007 and EOP-010 Seminar
Effects of Space Weather on Power Systems
Solar disturbances can release clouds of high energy plasma into space during coronal mass ejections. If a plasma cloud crosses the earth’s path it interacts with the earth’s magnetic field to produce geomagnetic disturbances (GMD). During geomagnetic disturbances variations in geomagnetic (at frequencies in the order of 1‑100 mHz) induce voltages in relatively long transmission lines at ground level, which in turn can result in quasi-dc induced currents (GIC) that can see their way into power transformers causing asymmetric saturation. The ac power system is not designed to handle dc currents over long periods of time (from hours to days). A GMD event caused an 8 hour, wide area blackout in Quebec in March 1989. This presentation will provide an overview of the physics of this phenomenon from an engineering perspective and the impact on the power system.
NERC reliability standards on Geomagnetic disturbances
NERC (North American Reliability Corporation) has issued two reliability standards to address the impact of geomagnetic disturbances (GMD) on the power system (230 kV and above). The first standard EOP-010 addresses operational measures and the second one TPL-007 addresses planning mitigation measures. Both standards are already in place and utilities and system operators in Canada are getting ready to achieve compliance. A Canadian variance on TPL-007 is in the process of being approved by NERC. This presentation will provide an overview of these standards and their impact on system operators and asset owners (such as the IESO, Hydro One and OPG in Ontario), both in terms of required system studies and the potential cost of mitigation measures to achieve compliance.

Dr. Luis Marti of IEEE Toronto PES Chapter
Biography:
Luis Marti (IEEE Fellow 2015) received MASc and PhD degrees in Electrical Engineering in 1983 and 1987, respectively, from The University of British Columbia. He joined Ontario Hydro (now Hydro One) from 1989 to 2016, where he was responsible for the Special Studies group. Research/study activities have included the development of models for the family of EMTP programs, GIC simulation, grounding, induction coordination, EMF issues pertaining to T&D networks, and technical issues around the connection of renewable generation in distribution networks. He has participated in a number of Canadian and international technical organizations such as CSA (Canadian Standards Association, IEEE, and CIGRE. He served as vice chair of the NERC GMD standard development team for TPL-002. He has served as an adjunct professor at the universities of Toronto, Waterloo, Western Ontario and Ryerson. He is currently active as president of a consulting firm focusing on GMD-and EMTP studies/research.
