The invention discloses a power-cut scheme scheduling scheme optimization method based on an overall distribution network. The overall distribution network not only comprises a traditional power distribution network rack and but also comprises a distribution network load and a distributed power supply. The method solves the problem that when scheduling staff works out a scheduling scheme for a power-cut scheme, they usually only consider current conditions of the power distribution network rack and can not formulate the scheduling scheme from the aspects of the overall distribution network of network, power and load. The method fully utilizes information of multiple aspects of the network, the power and the load, the scheduling scheme is analyzed and formulated for the power-cut scheme from the aspects of safety, economy, efficiency, intelligence and the like, power supply reliability and quality of users are improved, a scheduling level of the scheduling staff is improved, and the economy and the safety of the power distribution network are improved.
