Development directions in mobile energy storage technologies are envisioned. Carbon neutrality calls for renewable energies, and the efficient use of renewable energies requires energy storage mediums that enable the storage of excess energy and reuse after spatiotemporal reallocation.
While previous research has optimized the locations of mobile energy storage (MES) devices, the critical aspect of MES capacity sizing has been largely neglected, despite its direct impact on costs. This paper introduces a two-stage optimization framework for MES sizing, pre-positioning, and re-allocation within NMGs.
A mobile energy storage system is composed of a mobile vehicle, battery system and power conversion system . Relying on its spatial–temporal flexibility, it can be moved to different charging stations to exchange energy with the power system.
The optimal scheduling model of mobile energy storage systems is established. Mobile energy storage systems work coordination with other resources. Regulation and control methods of resources generate a bilevel optimization model. Resilience of distribution network is enhanced through bilevel optimization.
With the advancement of battery technology, such as increased energy density, cost reduction, and extended cycle life, the economy of mobile energy storage systems will be further improved. Future research should focus on the impact of new technologies on system performance and update model parameters in a timely manner.
During emergencies via a shift in the produced energy, mobile energy storage systems (MESSs) can store excess energy on an island, and then use it in another location without sufficient energy supply and at another time, which provides high flexibility for distribution system operators to make disaster recovery decisions .
Simulation results demonstrate that the proposed model significantly reduces the total operating cost of the microgrid compared to traditional methods. It also improves the profitability of EV users to a certain extent, promoting
