Network Attack Detection and Defense Mechanisms in Smart Grid

With the wide application of renewable energy, smart grid gradually becomes the core of power system. However, the network security problem of smart grid is increasingly prominent, facing a variety of network attack threats. This paper discusses the types and detection methods of network attacks in smart grid, analyzes the main security threats at present, and puts forward the corresponding defense mechanism. Through the evaluation of existing detection technologies, combined with the challenges of new attack and defense technologies, this paper aims to provide effective protection for the safe operation of smart grids and promote sustainable development in the future energy field.
