English: Concern has been raised that the electrical grid of this nation is vulnerable to prolonged collapse. The postulated mechanisms are geomagnetic storms, electromagnetic pulse attacks (EMP) via a high altitude nuclear detonation, cyberattacks, and kinetic attacks.
A point on a grid having a number of machines with an SCR above a number between 1 and 1.5 has less vulnerability to voltage instability. Hence, such a grid is known strong grid or power system. A power system (grid) having a lower SCR has more vulnerability to grid voltage instability.
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 ...
One of the key issues for electric grid security is that these ongoing improvements and modernizations have created more risk to the system. 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]
Attack tree for computer viruses. Here we assume a system such as Windows NT, where not all users have full system access.All child nodes operate on OR conditions. Attack trees are multi-leveled diagrams consisting of one root, leaves, and children.
The duck curve is a graph of power production over the course of a day that shows the timing imbalance between peak demand and solar power generation. The graph resembles a sitting duck, and thus the term was created. [2] Used in utility-scale electricity generation, the term was coined in 2012 by the California Independent System Operator. [3] [4]
Industroyer [1] (also referred to as Crashoverride) is a malware framework considered to have been used in the cyberattack on Ukraine's power grid on 17 December 2016. [2] [3] [4] The attack cut a fifth of Kyiv, the capital, off power for one hour and is considered to have been a large-scale test.
In a power system, a load curve or load profile is a chart illustrating the variation in demand/electrical load over a specific time. Generation companies use this information to plan how much power they will need to generate at any given time. A load duration curve is similar to a load curve. The information is the same but is presented in a ...
