Zhou Qingping, Xu Min.The role and benefits of pumped storage power stations in the construction of multi-energy complementary power systems in Guizhou. 2018. Hongshuihe. 37.
First, energy storage configuration models for each mode are developed, and the actual benefits are calculated from technical, economic, environmental, and social perspectives. Then, the CRITIC method is applied to determine the weights of benefit indicators, and the TOPSIS method is used to rank the overall benefits of each mode.
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.
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.
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.
