Abstract: In order to solve the problem of periodical and seasonal overload/heavy load in the 10 kV station area of the distribution network, a mobile energy storage system with a power of 100 kW and a capacity of 400 kW·h was developed to flexibly reinforce the 10 kV station area of the distribution network, to avoid repeated investment in the power grid during the transition period. The scheme designs, control strategy, engineering practice, etc. of the mobile energy storage system are described. The actual application shows that use of a mobile energy storage system with flexible configuration and convenient movement can effectively solve the current problem of weak power grid, and avoid repeated construction of the distribution network during the transition period, and it is an innovative solution to the problems of distribution network over/overload and low power supply reliability.
Key words: mobile energy storage; flexible reinforcement of power grid; control strategy; battery management system
