Abstract: Smart grid prediction analysis (SGPA) is the basis to ensure the economic and safe operation of power system. With the breakthrough of AI and the big data environment for smart grid, AI based SGPA is significant for the development of power system, thus this paper proposes “AI+” prediction. Firstly, the background of AI and SGPA and some related issues are introduced. Then based on different emphasis, the AI applications in renewable energy prediction, load prediction, steady state voltage stability prediction and related preventive measures are reviewed and future direction of the research content is prospected. In addition, other related technologies involved in prediction (sample generation, imbalanced data and features extraction) are summarized. Finally, limitations and future developments about AI are discussed and suggestions and ideas are proposed.

Key words: smart grid, “AI+” prediction, sample generation, imbalanced data, features extraction
