In this mode, new energy power plants form a consortium to jointly invest in and build an energy storage station. Once the energy storage station is constructed, it operates as an independent entity, serving multiple new energy power plants that participated in the investment.
The subsequent profits of the energy storage station can be distributed to the participating new energy power plants through game-theoretic methods, such as Nash bargaining or Shapley value, or according to the predetermined investment proportions in the contract.
The constraints that the energy storage station must satisfy include the capacity and power constraints of the energy storage configuration, as well as the constraint on the unit cost of the energy storage service. The capacity and power constraints are shown in Eqs. (10 – 11). The unit cost constraint of the energy storage service is as follows:
In the three scenarios, with the distinction between the two methods of energy storage capacity configuration, it is clear that the storage capacity of the energy with the surplus power online presents far less than with surplus power offline in local equilibrium.
For instance, in Guangdong Province, new energy projects must configure energy storage with a capacity of at least 10% of the installed capacity, with a storage duration of 1 h . However, the selection of the appropriate storage capacity and commercial model is closely tied to the actual benefits of renewable energy power plants.
In the shared mode, the energy storage is collectively owned by a consortium of new energy power plants, with the individual plants within the consortium serving as the users. Due to these differences in ownership and usage rights across the modes, the energy storage configuration schemes also differ.
