Investors can maximize future profits and reduce risks with ESS investment strategies. Energy storage systems (ESSs) are widely recognized as a possible solution for integrating the increasing renewable energy penetration in electrical grids.
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.
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.
Energy storage systems (ESSs) are widely recognized as a possible solution for integrating the increasing renewable energy penetration in electrical grids. However, ESS investments have many uncertainties, such as curtailment effects, incentive value, cost overruns, and delays in construction levels.
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.
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.
