Artificial intelligence (AI) plays a crucial role in the intelligent development of China’s power system. It is also an important part of the digital development of the power grid. The development of AI determines whether the digital transformation of China’s power system can be successfully implemented. Therefore, this paper discusses the digital transformation of the power grid based on AI technologies. The author has established a digital evaluation index system to reflect the development of the power grid in one province. Both qualitative and quantitative methods have been adopted in the analysis, which delves into the economic effectiveness, quality, and coordination of power grid development in the province in a comprehensive way. Results show that, to meet the needs of the power grid’s digital transformation, the correlation coefficient between the power grid’s development and the province’s overall coordination has been increasing in recent years.
