Abstract

As evidenced by the variety of papers submitted to this journal on the subject, space weather influences on electric grid systems around the world have been attracting increasing interest as solar cycle 24 continues to evolve. The paper by K. F. Forbes and O. C. St. Cyr contained in this issue of Space Weather Quarterly (and published earlier in the online Space Weather journal) is an example of such examinations of electric power systems. Using variations of the geomagnetic field as a proxy for geomagnetically induced currents (GICs) in an eastern U.S. electric grid, these authors find through a sophisticated statistical study that operations of the PJM Interconnection regional transmission organization were "challenged by geomagnetic activity" during solar cycle 23. Evidently the control systems in place by the transmission organization adjusted for grid effects that were apparently caused by GICs, even those of low magnitude. © 2012.
