Artificial Intelligence and Internet of Things Applications in Smart Grid Security: A Survey

This paper presents a survey of different artificial intelligence (AI) applications in the modern electric grid known as smart grid from security perspective and further highlights the importance of Internet of Things (IoT) in smart grid. IoT is used to connect devices in smart grid over the Internet without human intervention for controlling and monitoring the smart grid infrastructure. Large volume of data is generated from these IoT devices in the smart grid. These devices also provide proper load forecasting and data gathering for low cost. IoT devices and data transmitted between them in smart grid is more prone to security attacks. In this paper, different security issues and solutions to them in smart grid using AI techniques are explained in detail. The paper begins with the overview of smart grid communication system architecture followed by the role of IoT in smart grid. Later on, how AI techniques are used to overcome security threats in smart grid is presented comprehensively.
