A systematic method for the detection of attacks against sensors of the power grid is developed using Kalman filtering and statistical decision making criteria. The Kalman filter is used as a virtual sensor that emulates the functioning of the grid’s sensors in the fault-free mode. The output of the Kalman filter is compared against the output of the real sensors and the resulting differences generate...
A major aspect in power line distribution networks is the constant monitoring of the network properties. With the advent of the smart grid concept, distributed monitoring has started complementing the information of the central stations. In this paper, power line communications modems deployed throughout the network provide a tool to monitor high-frequency components of the signals traveling through...
