“…In [18], based on the current state of the network, the transmission lines, which act as an antenna, are switched to decrease the reactive power loss due to GIC. The method presented in this paper is not dependent on topology because it is tested on different types of test systems.…”

“…In [18, 19], line switching is considered as a method of mitigation of the GIC and reactive power loss of the transformers in large‐scale power systems. In [20], an optimal line switching is proposed along with a sensitivity analysis of optimal switching decisions with respect to the GMD direction.…”

“…This control circuit is integrated with a series capacitor device that is connected between neutral point-of-power transformers and ground. Furthermore, in [101,189,[227][228][229], mitigation of GIC effects based on operational methods are presented. In [189], an optimal placement technique of GIC blocking devices to minimize the cost of these devices is proposed.…”

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.

“…GMDs have the potential to severely disrupt operations of the electric grid by inducing quasi-dc GICs in the power grid, which may increase the reactive power losses and temperatures of transformers [28]. Thus, we create a scenario, which simulates an extreme geomagnetic storm event impacting the South Texas area, to give operators an immersive experience of how GMDs will affect the grid and what actions are needed to mitigate the impact.…”

Modern power systems are increasingly evolving cyber-physical systems (CPS) that feature close interaction between information and communication technology (ICT), physical and electrical devices, and human factors. The interactivity and security of CPS are the essential building blocks for the reliability, stability and economic operation of power systems. This paper presents a web-based interactive multi-user power system simulation environment and open source toolset (W4IPS) whose main features are a publish/subscribe structure, a real-time data sharing capability, role-based multi-user visualizations, distributed multi-user interactive controls, an easy to use and deploy web interface, and flexible and extensible support for communication protocols. The paper demonstrates the use of W4IPS features as an ideal platform for contingency response training and cyber security analysis, with an emphasis on interactivity and expandability.In particular, we present the use cases and the results of W4IPS in power system operation education and security analysis.
