The invention discloses a maximum power supply capability calculation method for a flexible power distribution network, and the method comprises the steps: 1, building a flexible power distribution network TSC mathematic model; 2, deforming the mathematic model at step 1, and inputting the deformed mathematic model into linear planning software for solving; 3, carrying out the further processing of a solving method, enabling each feed line not to be under the condition of heavy or light loads during the implementation of TSC, and obtaining a flexible power distribution network TSC balanced mathematic model. Compared with the prior art, the method verifies the accuracy of the model through conventional N-1 fault verification simulation. The method has already been used in the development verification of a medium voltage distribution network demonstration project in domestic and overseas multi-terminal flexible closed loop, and has the practical guidance significance for the demonstration project. 本发明公开了种柔性配电网的
