Geomagnetic disturbances (GMDs), caused by solar coronal mass ejections, have the potential to significantly impact the operation of the high voltage electric grid by causing geomagnetically induced currents (GICs). Over the last decade there has been significant research, industry interest, and regulatory concern about the impact of GMDs on the high voltage electric grid. The purpose of this two-day short course is to put the GMD issue into proper perspective by providing a comprehensive coverage of what is currently known about the impact of GMDs on the grid, the tools being used for their assessment in planning and operations, and the current areas of research.
The course philosophy is to provide in-depth coverage of the topics, but to do so using a practical, hands-on approach. For example, the course provides a detailed consideration of what is needed to do the GMD assessments required for NERC TPL-007-1, and also contains an interactive, real-time simulation of the operational impacts of GMDs on the grid. Throughout the course concepts will be illustrated using common industrial tools including those from EPRI and PowerWorld Simulator. Collectively the four course instructors have wide experience in this area doing electric power system studies, software tool development, research and engineering education (Hours: CEU 1.8, PDH 18).
Who Should Attend
The course is designed to provide a comprehensive coverage of the impacts of GMDs on high voltage electric grids. It is ideally suited for electrical engineers who work in the areas associated with either electric grid planning or operations, and for new graduates who would like to rapidly gain experience in the area of GMD grid impacts. The course will also be useful for technical staff in regulatory agencies, for technical managers, for academics wishing to gain practical knowledge in this important area, and for graduate students interested in careers in the power industry.
