An introduction to geomagnetic storms and the hazards they pose at the Earth’s surface  Geomagnetic storms are a type of space weather event that can create Geomagnetically Induced Currents (GICs) which, once they reach Earth’s 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 GICsData and methods used to analyze and forecast GIC hazardGIC impacts on the infrastructure of the bulk power systemAnalysis techniques used in different areas of GIC researchNew methods to validate and predict GICs in transmission systems
