Aiming at the power fluctuation of the distribution network caused by the fluctuation of renewable energy output in the sending-end power grid. In this paper, a coordinated optimization method of mobile energy storage for distribution networks with a high proportion of renewable energy sending end systems is proposed to improve the energy support of the sending end distribution network and improve the resilience of the distribution network. Firstly, based on the mobile characteristics of mobile energy storage, a space-time transfer and charge-discharge model of mobile energy storage based on the traffic network is established. Secondly, by analyzing the network structure of the distribution network of the sending end system. The mobile energy storage scheduling mode is adopted, and the mobile energy storage support model of the sending end system is established with the minimum cost of load shedding and the minimum cost of mobile energy storage scheduling. Then, the power balance of the sending end system and the power balance of the distribution network are respectively targeted. The power balance equation of the sending end system based on the balance constraint of charging and discharging of mobile energy storage is established. Finally, a distribution network in the sending-end system is taken as an example for simulation. It is verified that the strategy proposed in this paper can effectively improve the stability of the sending power of the sending end system and maintain the balance of the distribution network.
