The embodiment of the invention provides a distribution transformer region capacity identification method and device, a storage medium and an electronic device, which are applied to a Yyn0 type transformer. The method comprises the steps that a number of voltage differences of an area to be tested within a first preset time period and a current difference corresponding to each voltage difference are collected; a number of voltage differences and a number of current differences are input into a pre-established capacity fitting model to acquire capacity parameters corresponding to the area to betested; and the capacity corresponding to the area to be tested is acquired according to the capacity parameters and a number of preset standard capacity parameters, wherein the capacity is used to identify the load energy consumption corresponding to the area to be tested. According to the embodiment of the invention, the voltage differences and the current differences of the area to be tested are collected; the capacity parameters corresponding to the area to be tested are acquired according to the capacity fitting model; by comparing the capacity parameters with the standard capacity parameters, the capacity corresponding to the area to be tested is acquired; the capacity of the area to be tested is quickly identified; and excessive calculation steps are omitted.
