High-voltage power distribution network residual power supply capacity hierarchical calculation method

The invention belongs to the technical field of high-voltage power distribution, and discloses a high-voltage power distribution network residual power supply capacity hierarchical calculation method.The method comprises the steps of firstly obtaining a to-be-evaluated high-voltage power distribution network topological structure, power grid equipment parameters and current maximum load data; dividing the to-be-evaluated high-voltage power distribution network into a plurality of independent power supply areas; equivalently processing transformer substations in the independent power supply areas; calculating the residual power supply capacity of all the independent power supply areas; and finally, summarizing the residual power supply capacities of all the independent power supply areas to obtain a hierarchical evaluation result of the residual power supply capacity of the to-be-evaluated high-voltage power distribution network. The method is used for carrying out hierarchical calculation and evaluation on th
