The approach was implemented and tested in a real-time simulation unit, where a defined distribution grid provides simulated voltage data. An analysis of transmitted samples on a receiver and computation device according to power quality measurements and their limits due to dynamic behaviour is done. The goal of our proposed anomaly detection is in contrast to previous approaches to detect disturbances caused by cyberattacks on ICS components in distribution grids based on an open communication interface. This paper defines the first part of detection at a local node in a defined grid configuration.enanomaly detectioncyber securityIEC 61850-9-2004670conference paper
