Abstract: The new power system is mainly based on clean energy and utilizes massive data and computing technology to balance power sources and loads dynamically. Its core feature is the system's observability, measurability, and controllability. Artificial intelligence, as an important technological support, can enhance the intelligent perception level of the power grid and optimize the utilization of communication network resources and system data processing capabilities based on deep integration of energy flow and information flow. We mainly introduce the form, characteristics, and mechanism of the new power system, emphasizes the urgent need for digital transformation of the power grid in the new situation, and analyze the research status and application of artificial intelligence technology in the fields of power sensing, power communication, and power big data processing. Moreover, we explore its promotion of comprehensive perception, instant communication, and data analysis of electrical quantity, state quantity, and environmental quantity in each link of the new power system, powerfully supporting advanced applications of electricity. Finally, a summary and outlook on the challenges faced by artificial intelligence technology in constructing new power systems are presented.
