The Estimation of the Geomagnetically Induced Current Based on Simulation and Measurement at the Power Network: A Bibliometric Analysis of 42 Years (1979–2021)

GIC (geomagnetic induced current) is a natural current that flows through a conductive substance. The purpose of this study is to provide bibliometric analysis on the computation of the GIC at the Power Network, since determining the backflow current’s threshold limit is crucial to avoid electrical equipment failure. The methodology of the study includes topics, scope, and eligibility, as well as screening and an analytical screen paper. From 1979 to 2021, we investigate the evolution of bibliometric studies on the assessment of the GIC at the power network. According to the statistics, there are 601 Scopus articles and 357 Web of Science (WoS) papers in the study on GIC at the power network that focus on estimation from 1979 to 2021. According to the data, the Engineering and Energy disciplines contribute the most to research on predicting the GIC at the Power Network. The words “geomagnetically induced current,” “reactive power,” and “geomagnetism” are commonly used instead of “magnetic storm,” “power grids,” and “geoelectric fields.” The bibliometric method encompasses themes, scope and eligibility, screening, and screen paper for all publications in a search for developing subjects based on Scopus and WoS to map the time-trend, disciplinary distribution, and high-frequency keywords.
