As an example, one risk specifically comes from the integration of digital communications and computer infrastructure with the existing physical infrastructure of the power grid. [6] In the 2010s and 2020s, attacks to the United States electrical grid have become more frequent, with 2022 being the year with the most attacks. [7]
International Spy Museum exhibit for the Aurora Vulnerability. The failure of even a single generator could cause widespread outages and possibly cascading failure of the entire power grid as occurred in the Northeast blackout of 2003. Additionally, even if there are no outages from the removal of a single component (N-1 resilience), there is a ...
On December 23, 2015, the power grid in two western oblasts of Ukraine was hacked, which resulted in power outages for roughly 230,000 consumers in Ukraine for 1-6 hours. The attack took place during the ongoing Russo-Ukrainian War (2014-present) and is attributed to a Russian advanced persistent threat group known as "Sandworm". [1]
The experiment used a computer program to rapidly open and close a diesel generator's circuit breakers out of phase from the rest of the grid and explode. This vulnerability is referred to as the Aurora Vulnerability. The number and sophistication of cyber attacks is on the rise.
A vulnerability assessment is the process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities in a system. Examples of systems for which vulnerability assessments are performed include, but are not limited to, information technology systems, energy supply systems, water supply systems, transportation systems, and communication systems.
Similar concerns exist in Germany, where in 2005, a "cyber squirrel" crippled the entire electrical grid south of the River Elster for an hour. This squirrel was described as "a furry suicide bomber" ("pelzige[r] Selbstmordattentäter"). [24] Squirrels have been the cause of many power outages in Pennsylvania.
Performing a probabilistic risk assessment starts with a set of initiating events that change the state or configuration of the system. [3] An initiating event is an event that starts a reaction, such as the way a spark (initiating event) can start a fire that could lead to other events (intermediate events) such as a tree burning down, and then finally an outcome, for example, the burnt tree ...
Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components ...
