The Application and Threat of the Internet of Things in the Smart Grid

Various smart grids have been being designed and deployed to make up for shortfalls in power systems. The Internet of Things (IoT) technology is one of the supporting technologies for the smart grid system. The smart grid integrates all kinds of equipment to monitor, regulate, and analyze the power grid with IoT technology. In this paper, we mainly discuss the practical applications of the IoT in the smart grid and the advantages of these applications over traditional power systems. The IoT has its vulnerabilities, and it has a more complex and huge architecture after being combined with the smart grid. To avoid becoming a victim of grid reform and transformation based on the IoT, it is necessary to conduct in-depth research on the security of the smart grid. Therefore, in the context of practical cases, this paper summarizes the main security threats faced by the smart grid and lists relevant researches. This paper aims to facilitate the further application of IoT in the smart grid system.
