Background

Geomagnetically Induced Currents (GICs), generated by variations in the Earth's magnetic field during space weather events, present a significant hazard to critical ground-based infrastructure, notably impacting power transmission lines, electrical grids, railway signaling systems, and submarine communication cables.

While the space weather drivers of ground magnetic field fluctuations and the resultant induced ground electric fields are subjects of established research and growing understanding, the consequential effects of GICs on the operational systems (e.g., power grids) and overall integrity of power systems remain comparatively less explored. These knowledge gaps represent a critical impediment to both the accurate modeling and effective observation of GIC impacts, as well as the robust quantification of the risks and hazards posed by space weather-driven GICs.

This Research Topic specifically invites submissions that address the multifaceted impacts of GICs on ground power systems. Furthermore, this solicitation encourages contributions that elucidate the underlying magnetospheric and ionospheric processes that drive the generation and flow of GICs, alongside case studies and analyses of specific geomagnetic storm events.

Relevant areas of investigation for this Research Topic include, but are not limited to:

-Impacts of GIC-driven total harmonic distortion on power system components.
-Analysis and modeling of transformer thermal issues and potential damage during geomagnetically disturbed periods.
-Quantification and modeling of various potential impacts of GICs on power system performance under both geomagnetically disturbed and quiet conditions.
-Operational and control challenges arising from GIC effects in power grids.
-Development and application of monitoring techniques for GICs and their consequences in power infrastructure.
-Strategies for mitigating the adverse effects of GICs on power systems.

We welcome submissions employing observational data analysis, theoretical modeling, and data science approaches relevant to the aforementioned topics.

This Research Topic encourages the submission of various article types, including Original Research papers, Perspective articles, Opinions, Review articles and Mini-Review articles, as well as Hypothesis and Theory papers, that contribute to advancing our understanding of the critical relationship between space weather, GICs, and ground power systems.

The study of GICs is inherently interdisciplinary, bridging geophysics, space physics, and applied physics. While GICs are geophysically driven, their impacts extend deeply into applied physics domains, such as electrodynamics, materials science, and the physics of complex systems. Thus, we invite contributions that reach beyond the traditional geophysics community—engaging physicists working on plasma physics, nonlinear dynamics, energy systems, and infrastructure resilience. This broader perspective is essential for developing a comprehensive understanding of GIC phenomena and their technological consequences.

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
