Cyber attack detection in smart grids

Nowadays smart (energy) grids are used more than ever. This makes the smart grids more tempting for hackers and cyber-attacks, because the grids are a critical infrastructure and hackers could profit from this. The reason cyber-attacks are also aimed at smart grids is because of the vulnerability in communication technologies. In this paper, new detection methods against cyber-attacks are investigated. The new detection method is implemented in a simulation that is based on reality and uses data about the potential energy in an electric field and the electric current. One of the detection methods determined with a 94% accuracy if there was a cyber-attack and the other detection method prevented 91% cyber-attacks from happening.
