“…The module provides the user the ability to apply different geoelectric fields, such as uniform, non-uniform, benchmark, and local hotspots, with varying values of up to 20 V/km with storm directions from (0-360°), in the system for GIC analysis. Additionally, there are many software systems available to model power systems and GIC studies, especially for harmonic analysis [124]…”

“…These collisions result in ionization of the atmospheric layer and create an electromagnetic signal that might interact with electrical power networks and lead to GIC [120,121]. Several reviews regarding GMD and GIC effects and modelling of power systems have been performed by other researchers [22,39,46,[122][123][124][125]. However, much significant information has been neglected, and none of the studies have covered the phenomenon in a comprehensive manner.…”

“…The study in [123] focused only on modelling the induced geoelectric and geomagnetic fields with respect to GICs. In [124], the researchers mostly focused on modelling and simulation of GIC in the power system. In [125], the work is focused on GICs and space weather with respect to research in Austria.…”

Geomagnetically induced current (GIC) has been a significant concern for the electrical power grid in high latitudes for decades. Its origin starts in the Sun; during extreme space weather, the magnetic field of the Earth varies rapidly. This variation induces electric fields at the Earth's surface and leads to GICs in manmade technologies. Power systems are the most affected by this induced current, which causes halfcycle saturation of power transformers and other issues. Understanding the behaviours and chain effects of this phenomenon is the key consideration in modelling the hazards to technological systems from space weather. In this paper, a comprehensive review of space weather, geomagnetic disturbances (GMDs) and GICs and their impacts on the power systems in both high and mid-low latitude regions is presented. Additionally, we highlight the most commonly used methods to model and calculate geoelectric fields at the Earth's surface and GIC in the power systems with respect to DC and AC analysis. In addition, we have classified the GIC effects on the different power system components. Moreover, the possible solutions and mitigation techniques to eliminate or reduce these effects based on different GIC blocking devices are reviewed in this work. This work provides researchers and power system operators a shortcut road path to understanding GIC phenomena, modelling and calculations, effects, and mitigation of these effects.
