The invention discloses a method for evaluating a CIME power grid model based on an analytic hierarchy process. The method comprises the steps of: 1) definition of quality evaluation indexes of the CIME power grid model; 2) construction of a quality target structure map of the CIME power grid model based on the analytic hierarchy process; 3) construction of a judgment matrix for quality evaluationof the CIME power grid model; 4) consistency test on the judgment matrix for quality evaluation of the CIME power grid model; 5) and calculation of total hierarchical ranking of the quality of the CIME power grid model. The method disclosed by the invention is used for carrying out verification on various rules of a carrier CIM/E model file of each regional power grid model, and performing quality evaluation on each regional power grid model based on the verification result and combining with the analytic hierarchy process; and by adopting the evaluation method, the security of power grid model information can be improved, and the modeling quality of each regional power grid model is improved.
