“…These are series of electromagnetic waveforms that propagate to the Earth's surface; three main waveforms are generated during a detonation, among which the E3 late-time waveform produces electric fields with comparable time scales and area coverage as those of geomagnetic storm. However, these events are likely to have a higher peak field level resulting in greater impact and more severe damage than naturally-occurring solar flares [36,77].…”

“…Both GMD and E3 HEMP events pose a risk by generating low-frequency geomagnetically induced currents (GIC) that appear in the conductive infrastructure and flow into the high-voltage network through the neutrals of transformers [77,78]. GICs may adversely impact transmission systems and equipment as they have the potential to induce harmonics by causing half-cycle saturation in transformers.…”

Fundamental shifts in the structure and generation profile of electrical grids are occurring amidst increased demand for resilience. These two simultaneous trends create the need for new planning and operational practices for modern grids that account for the compounding uncertainties inherent in both resilience assessment and increasing contribution of variable inverter-based renewable energy sources. This work reviews the research work addressing the changing generation profile, state-of-the-art practices to address resilience, and research works at the intersection of these two topics in regards to electrical grids. The contribution of this work is to highlight the ongoing research in power system resilience and integration of variable inverter-based renewable energy sources in electrical grids, and to identify areas of current and further study at this intersection. Areas of research identified at this intersection include cyber-physical analysis of solar, wind, and distributed energy resources, microgrids, network evolution and observability, substation automation and self-healing, and probabilistic planning and operation methods.

“…This uncertainty can be quantified [4], and analyzed statistically [5] in order to guide the decisions regarding whether to accept certain modeling assumptions. Several GIC-oriented modeling tools have already been implemented, including harmonic generation and propagation, transformer thermal models, commercial power flows [6], and dynamic simulations [7]. This wide array of tools is crucial for modeling the power system to ensure safe and reliable operation, but it is also crucial to know which tools are appropriate to use in particular circumstances and to understand when a tool may not provide the necessary resolution.…”

Geomagnetic disturbances have been shown to disrupt the operation of the bulk electrical system through lowfrequency effects in the earth's magnetic field that in turn induce changing electrical fields on the earth's surface. As a result, geomagnetically induced currents flow in transmission lines, introducing the risk for widespread damage to high-voltage transformers and voltage collapse due to induced reactive power loss. In a previous work, the authors showed how certain modeling assumptions can lead to results that are unacceptable in certain edge case scenarios. In this paper, the authors build on their previous results using a probabilistic approach for uncertainty quantification in order to compare the results from electromagnetic transient program modeling software, ATP, to the positive-sequence calculation software, PowerWorld.
