Research on Multi-Time Energy Management Techniques for Shared Mobile Energy Storage Systems
Hanxin Zhang, Xingyu Dong, Wei Jiang · 2024
In response to the significant seasonal load characteristics and tight electricity demand in certain regions, a shared mobile energy storage system planning configuration and optimal dispatch method considering multiple time scales with power region characteristics is proposed. This method enables the optimal dispatch of multiple energy systems, taking into account specific application scenarios and considering cost comprehensively. Firstly, on a long-term time scale, the shared mobile energy storage systems are configured for seasonal loads on a monthly basis to maximize profits for the distribution. And it determines the capacity, power, and quantity of individual shared mobile energy storage units within the region. Then, on a short-term time scale, the method optimizes charging and discharging power of the mobile energy storage units and the connected nodes in the distribution network on a daily basis. This optimization aims to maximize the gains from peak-valley arbitrage and reducing network losses. The results of the case study demonstrate that the proposed method can significantly increase economic benefits while improving the spatiotemporal utilization of the energy storage system.
