The rapid development of smart grids and integrated energy systems, as well as power market reforms and new energy revolutions, has triggered an explosion of information in power systems. Massive power equipment and electrical appliances need advanced communication and computing technologies to support data collection and analysis. The Power Internet of Things is a smart service system that fully utilizes modern information technology, advanced communication technologies, and artificial intelligence to realize human-computer interaction, comprehensive status perception, efficient information processing, and flexible applications. It will effectively integrate communication infrastructure resources and power system infrastructure resources and improve the level of power system informatization. The Power Internet of Things will also improve the utilization efficiency of the existing infrastructure of the power system.

The theory and technology of power system information communication represented by power physical information systems and Power Internet of Things have attracted widespread attention. However, the power grid has its unique requirements and application conditions, such as the strict delay and reliability requirement on communication, rapid response to faults of the power grid, interaction between users and power system, etc. These features are very different from traditional computer networks and the Internet of Things and therefore lead to many challenges in the design and implementation of the Power Internet of Things.

This Special Issue aims to provide a platform for researchers to discuss the latest developments, research experience, and future development directions of theories and technologies related to the Power Internet of Things. High-quality research and review articles in related areas are welcome.
