The geomagnetically induced currents (GIC) caused by geomagnetic storms can inflict the anomalous operation of power systems, damaging electrical equipment, or even resulting in a large-area blackout of power systems. Therefore, to reduce the impact

The damage caused to power grid by geomagnetic storm increases with an increase in the grid voltage level and an increase in the grid coverage area. Xinjiang is a vast, high-latitude area in China, where geomagnetically induced currents (GIC) have an

Geomagnetic storm disasters have a significant impact on the safe and stable operation of power systems. Serious geomagnetic storm disasters can lead to cascading accidents in power systems, up to and including voltage collapse accidents. Therefore,

Geomagnetically induced currents (GICs) flowing through transformers affect their normal operation and can lead to accidents in power grids. The reactive power loss caused by GICs is called GIC-Q. At present, geomagnetic data are usually used to calc

Abstract The reactive power losses caused by the power grid Geomagnetically Induced Current (GIC) severely disturb the static voltage stability of power systems, and may even trigger voltage collapses. In this paper, the 1 V/km uniform induced geoele

Geomagnetically induced currents through the transformer windings produce biases of transformers, increase transformer reactive power losses, and lead to a significant lack of reactive power support in the power system. As a result, the geomagnetical

The reactive loss generated from the geomagnetically induced current (GIC) flowing through transformers has a characteristic of simultaneity in the whole power grid, which will result in a lack of reactive power, bring about voltage fluctuation and e
