Method and system for evaluating improvement of new energy acceptance capability of power distribution network, and medium

The embodiment of the invention discloses a method and a system for evaluating improvement of the new energy acceptance capability of a power distribution network by a flexible interconnection device, and a medium. The evaluation method comprises the following steps: acquiring first historical data of a new energy generator set and second historical data of the new energy generator set accessed to a flexible interconnection device; determining the first state total power of the new energy generator set according to the first historical data; according to the second historical data, determining the second state total power of the new energy generator set after the flexible interconnection device is accessed; and according to the first state total power and the second state total power, calculating the new energy acceptance capability increment of the power distribution network. According to the technical scheme provided by the embodiment of the invention, the new energy acceptance capability increment of the p
