“…4), stimulated by space weather effects on power systems (e.g., Albertson et al 1970Albertson et al , 1974Kappenman 1996). The large geomagnetic storm of March 1989 which blacked out Quebec, and the "Halloween storm" of 2003 produced a large increase in research and development related to geomagnetic storm effects on long conductors, both in the U.S. and in Europe (e. Pipelines are another class of long conductor that can be affected by anomalous space weather-induced telluric currents.…”

A somewhat personalized overview is presented of the effects of solar-terrestrial processes on electrical technologies, beginning with the electrical telegraphs in the mideighteenth century to the current era of extensive ground-and space-based commercial and governmental technical systems (including national security) upon which modern society depends. As human technologies increased in diversity over the last century and a half, space weather effects have continued to be of significant importance in the successful design and operations of many of these technologies.

“…The problems of geomagnetically induced currents in power lines and flowing in high voltage transformers have been recognized at least since the early 1970s (Albertson et al 1974), but were brought into serious consideration by the widespread failure of the HydroQuebec power grid (Canada) resulting from the severe geomagnetic storm on March 13-14, 1989 (Blais andMetsa 1993;Bolduc et al 1998). The estimated peak electrical power lost exceeded 20,000 MW and rendered millions of people problems for about 9 h. The problem occurs when quasi-DC (frequency range 0.01-0.0001 Hz) geomagnetically induced currents (GICs) flow between the high voltage lines and the Earth through transformer windings.…”

The time varying conditions in the near-Earth space environment that may affect space-borne or ground-based technological systems and may endanger human health or life are referred to as space weather. Space weather effects arise from the dynamic and highly variable conditions in the geospace environment starting from explosive events on the Sun (solar flares), Coronal Mass Ejections near the Sun in the interplanetary medium, and various energetic effects in the magnetosphere-ionosphere-atmosphere system. As the utilization of space has become part of our everyday lives, and as our lives have become increasingly dependent on technological systems vulnerable to the space weather influences, the understanding and prediction of hazards posed by these active solar events have grown in importance. In this paper, we review the processes of the Sun-Earth interactions, the dynamic conditions within the magnetosphere, and the predictability of space weather effects on radio waves, satellites and ground-based technological systems today.

“…This quasi DC will cause the transformer half wave saturation, which will cause [1][2][3] harmonic current increase, voltage drop, reactive power fluctuation and so on. Usually, high latitudes such as North America and North Europe, such as magnetic storms are strong and frequent, and GIC is harmful to the safe operation of the power grid [4][5].…”

“…The results of literature [12] show that the highest GIC of the substation in South Africa is up to 108A during the geomagnetic storm in March 13, 1989. According to the existing research, we can know that there are many factors that influence the GIC of power grid; especially the [13][14][15][16] disturbance at low latitudes is no longer the main factor affecting the GIC size of power grid. Therefore, low latitudes, especially the GIC near the equator, cannot be ignored.…”

Abstract.It is important to determine the possibility of high risk value of geomagnetic induced current (GIC), accurately define the level of power grid GIC, understand the distribution characteristics of disaster GIC, to prevent, control and evaluate the impact of magnetic storm disturbance on the power grid. Based on the full node model, the long term performance of 2003-2017 geomagnetic disturbances in Ethiopia 400kV-230kV power grid is analyzed. The results show that the probability of GIC high risk value of low voltage power grid in Ethiopia low latitude region is not zero. The GIC values in the northwest, Southeast and central regions are larger, and the GIC values in the northeast and southwest regions are smaller. When evaluating GIC, 400KV substations named S1, S2, and S8, S10, S48 and 230 kV substations such as S42, S43, S17, S16 and S53 should be monitored intensively. To ensure the calculation accuracy of high voltage power grid GIC is a prerequisite for the evaluation and governance of GIC. For GIC node accuracy, it is only need to consider the effect of 230kV grid on 400kV power system; For line GIC precision, it need to consider the influence of 230kV grid on 400kV power system and 400kV grid on 230kV power system.
