The invention relates to a multi-source access active power distribution network evaluation method comprising the steps that a three-level power network evaluation index system is set; specific index items included in each level of evaluation indexes are determined according to the evaluation content; the specific value of each index of the third level is calculated, and normalization processing is performed on each index according to the corresponding normalization processing strategy; the indexes included in each level form a judgment matrix according to the hierarchical structure scale, weight is set for the three-level indexes according to the analytic hierarchy process, and the judgment matrix is set by using the pairwise comparison method weight vectors are obtained; weighted averaging is performed level by level according to the specific value of the indexes of the third level and the weight of the indexes of the third level so that the value of the indexes of the second level and the first level is obtained, and finally the comprehensive evaluation score of a multi-source access active power distribution network in a certain region can be obtained; and the aforementioned steps are repeated and the comprehensive evaluation value of the multi-source access active power distribution network of each region is obtained, the comprehensive evaluation values of the multi-source access active power distribution networks of all the regions are compared, and the high comprehensive evaluation value indicates high level of aggregation of the multi-source access active power distribution network of the region.
