Distribution transformer weight and overload self-adaptive control method and system based on mobile energy storage

The invention discloses a mobile energy storage-based distribution transformer weight and overload adaptive control method and system. The method comprises the following steps of: obtaining rated capacity and an expected load rate of a transformer for supplying power to a power transmission line; acquiring the actual total load capacity of the power transmission line at the previous moment and the stored electric quantity consumed by the energy storage device for supplying power to the power transmission line; and based on the rated capacity, the expected load rate, the actual load total capacity of the power transmission line at the previous moment and the actual storage electric quantity consumed by the energy storage device, the output capacity provided by the energy storage device for supplying power to the power transmission line at the next moment is adaptively adjusted, so that the actual load rate of the transformer is within a specified range. According to the invention, the output capacity of the en
