Abstract: The artificial intelligence（AI） technology is an important driving force for promoting industrial development and technological innovation. However, the application of AI in power systems also faces many challenges because of insufficient accumulation of technology, inadequate technical standards, lack of high-dimensional and high-quality data, defects in deep neural network algorithms and so on. In this paper, the main technologies of AI and its application status in the power system have been sorted out, the technical application system based on the basic framework of basic equipment layer, data management layer, algorithm training layer, and application scenario layer have been analyzed. The technical measures that should be taken for the application of AI in power systems have been proposed. Finally, the prospects for the deep integration of the new generation of AI with power systems and the implementation of smart energy systems are presented.
