Disclosed is a power distribution network coordinated planning method considering a load transfer channel. The power distribution network coordinated planning method includes steps of determining an area, investigating and surveying to collect data, to be specifically, determining a plan area, and collecting data of current situations of the power distribution network in the plan area; analyzing the connection modes of the power distribution network; analyzing the load transfer channel of the power distribution network; analyzing adaptability of a typical power supply mode; analyzing coordination of the power distribution network; judging whether power supply is up to the maximum. The power distribution network coordinated planning method has the advantages that the load transfer channel is comprehensively considered for coordination of various voltage levels of the power distribution network, the typical power supply mode suitable for the power distribution network in the area is provided, scientificity and pertinence in planning are improved as well as safety and reliability of the power grid, investment to the power grid is reduced, and utilization efficiency of the power grid equipment is improved. Therefore, the power distribution network coordinated planning method is more scientific and complete, useful reference is provided for distribution network planning personnel about investment, and powerful technical support is provided for future power distribution planning. In addition, the power distribution network coordinated planning method is easy to master and operate.
