“…The technique of undergrounding the overhead distribution system is the most obvious solution and would prevent storms, lightning strikes or even trees from destroying lines and poles. However, this solution has high costs and it is not recommended since it does not guarantee the reliability of the system at 100% [89,92,93]. Another problem that this solution has is that when the distribution system is underground, the restoration time could increase due to the difficulty of accessing the cables.…”

“…On the other hand, for those portions that would not be underground, the structural reinforcement of the distribution system is another hardening solution used. Some of the suggested practices are to install guy wires or use steel or composite poles in order to reinforce the existent poles [92]. Also, to prevent and combat equipment water damage due to flooding or strong rains, the application of hydrophobic coatings or the application of grade B construction is mentioned, which is the stronger standard of construction [94].…”

A Survey on Power Grid Faults and Their Origins: A Contribution to Improving Power Grid Resilience

One of the most critical infrastructures in the world is electrical power grids (EPGs). New threats affecting EPGs, and their different consequences, are analyzed in this survey along with different approaches that can be taken to prevent or minimize those consequences, thus improving EPG resilience. The necessity for electrical power systems to become resilient to such events is becoming compelling; indeed, it is important to understand the origins and consequences of faults. This survey provides an analysis of different types of faults and their respective causes, showing which ones are more reported in the literature. As a result of the analysis performed, it was possible to identify four clusters concerning mitigation approaches, as well as to correlate them with the four different states of the electrical power system resilience curve.

“…Utilities are spending more on vegetation management and storm hardening, including tree trimming and upgrades to poles and fixtures. One of the key causes of the 2003 blackout was insufficient tree trimming [9][10][11]. Some utilities are considering whether there is economic justification for undergrounding their distribution lines to reduce exposure to environmental hazards [12][13].…”

Analysis of Determinants of the Impact and the Grid Capability to Evaluate and Improve Grid Resilience from Extreme Weather Event

2017

View full text Add to dashboard Cite

Concerns about the power outages caused by extreme weather events have led the study of grid resilience. Among the grid resilience studies, this paper presents an overview to evaluate and improve grid resilience through the analysis of determinants of the impact and the grid capability. The impact is determined by the extreme weather events, grid exposure, and grid vulnerability. Whereas, the determinants of the grid capability are physical durability, operational versatility, and rehabilitation capacity. Conceptual knowledge for quantifying the impact and the grid capability is also presented. Then, some improvement strategies to reduce the impact and to improve the grid capability based on their determinants are discussed. The study of the impact and the grid capability provides a preliminary guideline to plan appropriate grid resilience improvement strategies.
