Shared Energy Storage Optimizes Microgrid Performance

A study published October 1, 2025, details a shared energy storage model designed to improve regional microgrid efficiency. Researchers developed a bi-layer optimization method to cut costs and boost performance in these localized energy networks. The model focuses on user-side energy storage applications within a sharing economy framework. The research outlines operational and profit structures for shared energy storage stations. These stations play a key role in governing energy sharing within the microgrid. The bi-layer model aims to minimize operating expenses for the storage stations while simultaneously maximizing the economic output of the regional microgrids. The outer layer configures the energy storage stations, while the inner layer optimizes economic consumption rates and overall operations. Simulations showed a 15.12% decrease in microgrid operating costs after implementing the shared storage solutions. The new energy consumption rate also rose to 97.44%. The study projects that shared energy storage service providers can recoup their initial investment in approximately 4.62 years. The findings suggest the bi-layer optimization configuration effectively enhances the economic viability of both shared energy storage stations and the regional microgrids they serve.
