A Deep Learning Approach for the Automated Classification of Geomagnetically Induced Current Scalograms

Applied Sciences
During geomagnetic storms, which are a result of solar wind’s interaction with the Earth’s magnetosphere, geomagnetically induced currents (GICs) begin to flow in the long, high-voltage electrical networks on the Earth’s surface.

Modeling and Risk Assessment of Geomagnetically Induced Currents During Geomagnetic Storm in the 500 kV Power Grid of Guangxi, China

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Geomagnetic storms can induce geomagnetically induced currents (GIC) in power systems, posing threats to grid security. In this study, a GIC calculation model for the 500 kV power grid in Guangxi, China, is developed based on one‐dimensional (1D) and various three‐dimensional (3D) magnetotelluric (MT) impedance data.

Geomagnetically Induced Current Model Validation From New Zealand's South Island

Space Weather, 2020
Geomagnetically induced currents (GICs) during a space weather event have previously caused transformer damage in New Zealand. During the 2015 St. Patrick's Day Storm, Transpower NZ Ltd has reliable GIC measurements at 23 different transformers across ...

Linking Very Near‐Earth Reconnection (VNERX) to Mid‐Latitude GICs: Evidence From the 7 September 2017 Storm

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Geomagnetically Induced Currents (GICs) are a hazard to power systems. In this letter, we present a case study to understand why a Sudden‐Commencement‐associated 20A GIC spike, measured at mid‐latitude in Virginia, US, increased to 30A within 2 min of interplanetary shock arrival.

New Detailed Modeling of GICs in the Spanish Power Transmission Grid

Space Weather, 2021
The threat of Geomagnetically Induced Currents (GICs) driven by severe Space Weather looms over technological systems such as power grids. Assessing their vulnerability is thus vital to avoid damages or even disruption of the electrical power supply ...

Improvement in the modelling of geomagnetically induced currents in Southern Africa [PDF]

, 2016
One of the consequences of the geomagnetic storms resulting from adverse space weather is the induction of geomagnetically induced currents (GICs) in power lines. The GICs that flow in a power transmission network are driven by the induced electric field

Geomagnetically induced currents in a Norwegian transformer station [PDF]

, 2022
This report considers measurements of geomagnetically induced current (GIC) and comparison to recorded variations in the geomagnetic field (dB/dt). The GIC-sensors were installed in the neutral point of a 420 kV transformer located in Mid-Norway in 2019.

Mapping a Carrington Storm

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract A map is presented of median 1‐min‐resolution peak geoelectric‐field strength across the United States as would be induced by magnetic storms as intense as the 2 September 1859 Carrington storm. The map is constructed from two data sets: Magnetometer time series from 22 ground‐based observatories recording 40 magnetic storms, and surface ...
