On the supply side, as China''s energy strategy has always focused on fossil energy, which accounts for a higher proportion of primary energy consumption, and renewable energy accounts for a relatively low proportion, China will increase its national independent contribution and adopt more powerful policies and measures to strive for carbon dioxide
Then, different strategies are set based on the capacity allocation of energy storage in the two markets, and the energy storage station''s role and revenue are analyzed. Simulations under different participation strategies are done, the results show that with the increase of renewable energy connected to the grid, taking the energy storage more as an excellent frequency

This article establishes a full life cycle cost and benefit model for independent energy storage power stations based on relevant policies, current status of the power system, and trading rules of the power market. A typical electrochemical energy storage power station in Shandong is selected, and its economic value is analyzed by calculating
For the improved RO, comparing Case 2 to Case 4, we can see that with the addition of independent energy storage and SES, the alliance's ability to response to uncertainty increases, which makes the pole value shrink from 1 to 0.9, and then to 0.4, and the income increases twice, with the increase rates of 6.69% and 3.39% respectively.
If only rely on a single income model, the IRR of energy storage is approximately 2% based on current market standards in China, making it challenging to maintain the commercial viability of energy storage operations.
In the independent energy storage mode, each NEPS pursues its individual profit maximization goal, treating physical energy storage as an integral component rather than a separate entity. Each NEPS participates separately in the power-green certificate market, utilizing only its own PES.
Shared energy storage (SES). SES includes physical energy storage (PES) and virtual energy storage (VES). When the SES receives regulating demand signals from multiple NEPSs simultaneously, it integrates the scheduling demands of all NEPSs to determine the output of its PES and VES.
Although energy storage at some time can chase the profit of electricity price difference, charging in the low price period (13 h—14 h) and discharging in the peak period (19 h, 21 h), the regulation function of energy storage is not maximized due to the different charging and discharging conditions among different NEPSs.
To sum up, the energy storage power station can consider multi-channel income mode, and obtain satisfactory return on investment through the combination of “peak-valley price difference” + “capacity price” + “peak-shaving price” + “rental fee”. 6. Conclusion
