Geomagnetically Induced Currents from the Sun to the Power Grid [Hardcover]

An introduction to geomagnetic storms and the hazards they pose at the Earths surface?

Geomagnetic storms are a type of space weather event that can create Geomagnetically Induced Currents (GICs) which, once they reach Earths surface, can interfere with power grids and transport infrastructure. Understanding the characteristics and impacts of GICs requires scientific insights from solar physics, magnetospheric physics, aeronomy, and ionospheric physics, as well as geophysics and power engineering.

Geomagnetically Induced Currents from the Sun to the Power Grid is a practical introduction for researchers and practitioners that provides tools and techniques from across these disciplines. ?

Volume highlights include:

• Analysis of causes of geomagnetic storms that create GICs
• Data and methods used to analyze and forecast GIC hazard
• GIC impacts on the infrastructure of the bulk power system
• Analysis techniques used in different areas of GIC research
• New methods to validate and predict GICs in transmission systems
