High-voltage direct current (HVDC) has received considerable attention due to several
advantageous features such as minimum transmission losses, enhanced stability, and …

In this paper, the problem of harmonic coupling between the converter transformer and the
converter under the action of geomagnetically induced current (GIC) is proposed to be …

Geomagnetically induced currents driven by geomagnetic disturbances can cause half-cycle
saturation of transformers and consequently affect the power grid with reactive losses. The …

The power grid's geomagnetically induced currents (GIC) during geomagnetic storms, are
associated with a broad and abrupt harmonic impact, with the potential for grid paralysis and …

In the past few years, there has been a concerted effort to move towards renewable energy
sources and reduce dependence on fossil fuels in electricity production. This transition …

In this study, a switch-mode three-phase active tracking AC-AC voltage regulator based on
the boost converter is proposed with a moderate number of active and passive elements …

Geomagnetically induced currents (GICs) generated by magnetic storms are prone to cause
half-cycle saturation of transformers in the grid, which has the potential to severely disrupt …
