The invention discloses a superior and subordinate power grid layered collaborative optimization scheduling method considering power grid loss, and the method comprises the steps: building a superior power grid optimization scheduling model at a superior power grid level by taking the clearing electricity price considering the superior power grid loss and the electricity selling and purchasing quantity of a two-stage power grid as interactive variables; on the level of a lower-level power grid, the influence of spatial distribution of the electric vehicles on the power loss of the lower-level power grid is considered, an electric vehicle spatial scheduling layer is arranged, the spatial positions of the electric vehicles are optimized on the basis of the optimal time distribution of multiple types of scheduling resources of the upper-level power grid and the lower-level power grid, and then the power flow of the lower-level power grid is optimized, so that the power loss of the lower-level power grid is reduced. A parallel subspace algorithm is introduced to solve the model, so that frequent information interaction between upper and lower power grids is avoided, and the solving efficiency is improved; the effectiveness of the model is verified through simulation examples. According to the method, the power grid loss is reduced, and the overall economy of the power grid is improved.
