Book Description
Geomagnetic Disturbances Impacts on Power Systems: Risk Analysis & Mitigation Strategies provides a full risk assessment tool for assessing power systems confronted geomagnetic disturbances (GMDs) and specifies mitigation opportunities for various stakeholders. “This book deals comprehensively with the threat of solar storms on the world’s power systems. It provides a context to GMDs with respect to other natural hazards, and describes methods to evaluate a particular grid’s risk factors in a straightforward fashion. This is extremely useful to power grid operators, as they are not experts in the field of space weather, but they must be able to deal with its impacts. This is the critical message of this extremely valuable book.” – William A. Radasky, Ph.D., P.E., IEEE Life Fellow, Metatech Corporation, California USAAimed at risk engineers, policy-makers, technical experts and non-specialists such as power system operators, this book seeks to provide an insight into the GMD as a natural hazard and to perform the risk assessment of its potential impacts on the power systems as critical infrastructures. The reader gets familiar with how the Sun can endanger ground-based technological systems and the physics of solar activity manifestation on the Earth as Geomagnetically Induced Currents (GICs). The reaction of power systems to GMDs and mitigation strategies aiming at reducing and controlling the risks are then addressed. The GMD mitigation strategies, the power systems critical factors analysis, the high-risk zones identification and an estimation of economic loss, which is a valuable input for the (re)insurance sector, are also brought to the attention of the reader. Thereby, this book provides a full risk assessment tool for assessing power systems confronted with space weather risks. Key features: • Brings together interdisciplinary perspectives on the topic in one, cohesive book • Practical guideline on mitigation actions for diverse users and even non-specialists • Dealing comprehensively with the threat of geomagnetic disturbance on the worlds power systems • Introducing unique methods to evaluate a particular system risk factors in a straightforward fashion Authors Olga Sokolova, Ph.D., is a risk analyst and electrical engineer with expertise in the domain of critical infrastructure risk assessment to natural catastrophes.

Book Description
This comprehensive and up-to-date book presents the complex story behind the threat posed by massive solar storms to the electric grid. There is growing concern that a repeat of the colossal "Carrington-event" storm of 1859, or even the lesser 1921 solar storm, could wreak unprecedented havoc on America's electric power system, potentially causing prolonged blackouts. In a worst-case scenario, some researchers believe that a giant solar storm could catastrophically damage hundreds of huge high-voltage transformers critical to the grid; since the replacement of these components could take years, unimaginable consequences are possible. Here we have compiled dozens of official documents and reports that explain the threat and explore possible measures to limit the risk. Contents: Part 1: Overview of the Threat * Part 2: Federal Energy Regulatory Commission (FERC) Material * Part 3: U.S. Congressional Hearings * Part 4: Department of Homeland Security Evaluation * Part 5: Federal Emergency Management Agency (FEMA) Material * Part 6: Secure Grid '11: Electrical Grid Crisis Tabletop Exercise * Part 7: Large Power Transformer Study Report * Part 8: Space Weather * Part 9: The Sun, the Earth, and Near-Earth Space: A Guide. The nation's power grid is vulnerable to the effects of an electromagnetic pulse (EMP), a sudden burst of electromagnetic radiation resulting from a natural or man-made event. EMP events occur with little or no warning and can have catastrophic effects, including causing outages to major portions of the U.S. power grid possibly lasting for months or longer. Naturally occurring EMPs are produced as part of the normal cyclical activity of the sun while man-made EMPs, including Intentional Electromagnetic Interference (IEMI) devices and High Altitude Electromagnetic Pulse (HEMP), are produced by devices designed specifically to disrupt or destroy electronic equipment or by the detonation of a nuclear device high above the earth's atmosphere. EMP threats have the potential to cause wide scale long-term losses with economic costs to the United States that vary with the magnitude of the event. The cost of damage from the most extreme solar event has been estimated at $1 to $2 trillion with a recovery time of four to ten years, while the average yearly cost of installing equipment to mitigate an EMP event is estimated at less than 20 cents per year for the average residential customer. Naturally occurring EMP events resulting from magnetic storms that flare on the surface of the sun are inevitable. Although we do not know when the next significant solar event will occur, we do know that the geomagnetic storms they produce have occurred at varying intensities throughout history. We are currently entering an interval of increased solar activity and are likely to encounter an increasing number of geomagnetic events on earth. In 1989, an unexpected geomagnetic storm triggered an event on the Hydro-Quebec power system that resulted in its complete collapse within 92 seconds, leaving six million customers without power. This same storm triggered hundreds of incidents across the United States including destroying a major transformer at an east coast nuclear generating station. Major geomagnetic storms, such as those that occurred in 1859 and 1921, are rare and occur approximately once every one hundred years. Storms of this type are global events that can last for days and will likely have an effect on electrical networks worldwide. Should a storm of this magnitude strike today, it could interrupt power to as many as 130 million people in the United States alone, requiring several years to recover. Mitigation technologies to protect the power grid against such a costly EMP event can be developed, and in some cases do exist. - Federal Energy Regulatory Commission (FERC)
