The invention discloses an unbalanced active power distribution network optimization method and system based on a hybrid distribution transformer, and the method is based on a double-layer optimization method of a myxin algorithm, and comprises the steps: building an optimization cost function model at an upper layer; wherein the lower layer establishes an optimal scheduling model of the hybrid distribution transformer in the unbalanced active power distribution network, the result of the lower layer is returned to the upper layer, and the result of the upper layer and the result of the lower layer are synthesized to give an optimal scheduling scheme, so that the optimal scheduling of the hybrid distribution transformer in the unbalanced active power distribution network is realized. The hybrid power distribution transformer in the method can improve the problems of three-phase imbalance and unreasonable reactive power distribution of the unbalanced active power distribution network, and the position, the cap
