This paper introduces the construction status of distribution network in Xiong’an New Area and the application scenarios of mobile energy storage in xiong’an New Area.Aiming at the problems of low level of power grid equipment

weak network infrastructure and serious shortage of power supply capacity

this paper proposes a digital mobile energy storage system

and analyzes the system from the aspects of system architecture

energy storage conversion efficiency and control strategy

The advantages of the system in the flexible reinforcement of 10 kV distribution network and the solution of seasonal/periodic heavy overload in the transitional period are verified by an example.
