6 FAQs about [Independent energy storage operation mode]
What is independent energy storage?
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.

Design a cooperation mode of new energy power stations and shared energy storage. Divid the shared energy storage into physical energy storage and virtual energy storage. Propose a two-stage robust optimization model with improved uncertainty interval. Construct an entropy weight modified Shapley value-based benefit allocation strategy.
How does independent energy storage affect Ro?
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.
Can energy storage power station consider multi-channel income mode?
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
What is the IRR of energy storage based on a single income model?
