Regarding shared storage, Reference presents a shared energy storage capacity configuration model that combines long-term contracts with real-time leasing, addressing various modes.
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.
Comparing the three modes, it can be seen that the required energy storage scale is smallest in the shared mode, with a configuration capacity of 136.38 MWh and a configuration power of 36.19 MW.
In this section, based on the energy storage configuration results mentioned above, the actual benefits generated by these three commercial models are evaluated from four perspectives: technical, economic, environmental, and social. The specific descriptions of the evaluation indicators are as follows.
Research on optimal energy storage configuration has mainly focused on users , power grids [17, 18], and multienergy microgrids [19, 20]. For new energy systems, the key goals are reliability, flexibility , and minimizing operational costs , with limited exploration of shared energy storage.
New energy power plants can implement energy storage configurations through commercial modes such as self-built, leased, and shared. In these three modes, the entities involved can be classified into two categories: the actual owner of the energy storage and the user of the energy storage.
