Operational Strategy for Shared Energy Storage Considering Multiple Services Under High Clean Energy Penetration
摘要
Shared energy storage has multiple grid applications such as smoothing clean energy fluctuations and promoting clean energy consumption, but the development of shared energy storage faces problems such as low energy storage utilization and low economic benefits. Therefore, this paper proposes an economic operation strategy for shared energy storage considering multiple application scenarios under a high proportion of clean energy integration, and combines the shared energy storage operation mode with multiple economic evaluation indicators to assess the economic benefits of shared energy storage in the whole life cycle. Finally, the proposed strategy is validated using data from a coastal province. The results show the average internal rate of return and average payback period of whole network shared energy storage are 10.19% and 7.63 years respectively, which demonstrate that the shared energy storage operation strategy under multiple application scenarios can effectively improve the economic efficiency of shared energy storage, increase the proportion of clean energy consumption, and provide a reference for the realization of a clean, efficient, and reliable energy system.
