Although blockchain is best known for securing digital currency payments, researchers at the Department of Energy’s Oak Ridge National Laboratory are using it to track a different kind of exchange: It’s the first time blockchain has ever been used to validate communication among devices on the electric grid.
A sustainable energy supply requires the expansion of power grids. However, new transmission lines can also lead to grids becoming more unstable rather than more stable, as would be expected. This phenomenon is referred to as the Braess paradox. For the first time, an international team, including researchers from the Karlsruhe Institute of Technology (KIT), has now simulated this phenomenon in detail for power grids, demonstrated it on a larger scale, and developed a prediction tool, which is to support grid operators in decision-making. The researchers report in the journal Nature Communications. (DOI: 10.1038/s41467-022-32917-6)
Scientists have created a cybersecurity technology called Shadow Figment that is designed to lure hackers into an artificial world, then stop them from doing damage by feeding them illusory tidbits of success. The technology is aimed at protecting physical targets—infrastructure such as buildings, the electric grid, and water and sewage systems.
A simple sensor system developed at PNNL can prevent dangerous battery fires.
