Method for evaluating openable capacity of energy-storage-containing feeder line

The invention discloses a feeder openable capacity evaluation method containing energy storage, which considers the load time sequence characteristics of different types of user load peak values, andcomprises the following steps of: carrying out load classification according to historical data to obtain typical load time sequence characteristics; calculating constraint conditions of the openablecapacity safety boundary model containing the energy storage, and constructing the openable capacity safety boundary model containing the energy storage feeder line; and calculating the openable capacity of the energy storage feeder line. The method has the advantages that the original inherent mode that N1 verification is conducted only through the peak load of the distribution network and the power supply capacity is calculated is broken through, the load time sequence characteristics of existing users and newly-connected users are considered and distinguished, the concept of feeder line openable capacity is introduc
