The invention discloses an analysis method for the comprehensive energy-saving potential of a power distribution network. The method comprises the steps as follows: an index set affecting the energy-saving effect of the power distribution network is determined on the basis of a maximum potential energy-saving technology; all energy-saving technology factor sets are determined on the basis of the determined index set affecting the energy-saving effect of the power distribution network; on the basis of an analytic hierarchy process, all determined energy-saving technologies are compared, energy-saving potentials of all energy-saving measures are judged, and finally, the energy-saving technology with the maximum energy-saving potential is determined; and according to the energy-saving potentials, obtained through comparison, of different energy-saving technologies, an optimization modification scheme for forming the comprehensive energy-saving technology of the power distribution network is optimized. According to the analysis method for the comprehensive energy-saving potential of the power distribution network, the defects that the energy-saving effect is poor, the evaluation difficulty is large, and the like in the prior art can be overcome, and the advantages that the energy-saving effect is poor and the evaluation difficulty is small are realized.
