Energy storage power stations can explore a multi-channel income approach and achieve a favorable return on investment by combining “peak-valley price difference”, “capacity price”, “peak-shaving price” and “rental fee”.
Comparing Case 2, Case 3, it shows that the addition of energy storage makes it no longer necessary for the alliance to balance its own power generation deviation by buying and selling electricity for some time periods, such as 20 h; or significantly reduce the deviation of electricity, such as 13 h, 14 h.
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.
At present, there have been some research results on shared energy storage (SES), but the main research scenario is sharing between prosumers in communities [ 7, 8 ], and few studies have discussed energy storage sharing between power stations.
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
