Abstract

The present invention provides a smart grid attack detection method and device based on 5G communication, wherein the method includes: collecting power parameters of each device in the smart grid system based on 5G communication; using the Monte Carlo simulation method to predict the state of each subsystem at a future time according to the power parameters of each device in the smart grid system and the random state probability transfer matrix of each subsystem in the smart grid system established based on the Markov model; if there is a partial available state in the state of the subsystem at the future time, the unpowered energy loss value and the load value loss value of the subsystem in the partial available state within the simulation time are calculated; according to the unpowered energy loss value and the load value loss value of the subsystem in the partial available state within the simulation time, the risk of the smart grid being attacked from the outside is predicted. The present invention can quickly detect whether the smart grid is attacked from the outside, and greatly shorten the recognition and response time of the smart grid when it is attacked.
