There is no scenario in which a single plant independently changes the storage strategy or withdraws from the consortium.
Energy storage configuration models were developed for different modes, including self-built, leased, and shared options. Each mode has its own tailored energy storage configuration strategy, providing theoretical support for energy storage planning in various commercial contexts.
Simulation results validate the effectiveness of the proposed method and compare the benefits of the three modes, showing that the leased mode provides the highest overall benefit. This study provides a quantitative reference for the rational selection of energy storage modes in renewable energy projects.
The energy storage configuration should be converted to independent operation mode through technological upgrading. This transformation enables the original abandoned output power from the wind and solar can be stored and thereby increasing revenue through the consumption of otherwise discarded electricity.
The key difference from the leased mode is that, in the leased mode, the energy storage company configures storage on a one-to-one basis with each new energy power plant, whereas in the shared mode, the energy storage station configures storage on a one-to-many basis with multiple new energy power plants.
Despite the extensive research on energy storage configuration models, most studies focus on a single mode (such as self-built, leased, or shared storage), without conducting a comprehensive analysis of all three modes to determine which provides the best benefits for new energy plants.
