Power distribution network maintenance load transfer method for fused distributed power supplies and flexible loads

The invention relates to a power distribution network maintenance load transfer method for fused distributed power supplies and flexible loads. According to the power distribution network maintenance load transfer method for the fused distributed power supplies and the flexible loads, when a power distribution network is maintained, the sum of the deliverable power of all distributed power supplies in areas in power failure caused by maintenance is compared with the sum of the total power of load inside the areas in power failure, the total load of the flexible loads inside the areas in power failure and the capacity margin of primary support feeder lines connected with all the areas in power failure, a power supply recovery manner is determined according to comparative results, and the output power of each distributed power supply and the load capacity of the optimal flexible load needing to be cut are determined by using an optimal tide model after the power supply recovery manner is determined, so that the
