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.
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.
Regarding shared storage, Reference presents a shared energy storage capacity configuration model that combines long-term contracts with real-time leasing, addressing various modes.
According to the above model, the configuration model of energy storage in the self-built mode is a mixed integer planning problem, which can be solved directly by using the Cplex solver. In the leased mode, it is assumed that the energy storage company has adequate resources to generally meet the new energy power plant’s storage needs.
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.
