The grid planning AC operation mode generating method based on artificial is hard to meet the demand of effectiveness and power flow convergence. To solve this problem, this paper builds the mode of AC operation mode data generating according to the typical scene of AC operation mode preparation. Then it puts forward the key technologies based on K-means for the core part of the mode. Finally it is applied to analysis the practical problem of power grid in five areas in China, and the result suggests that the mode and algorithm in this paper are adequate for large-scale grid with new energy, and can improve the efficiency of operation mode generating.
