In summary, the economic performance of the energy storage power station is mostly affected by rental fees and the heat price, the price of auxiliary service also exerts a great impact on the economy, while the impact on the economy of cost per unit capacity of energy storage and downtime is less significant.
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
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.
Energy storage stations have different benefits in different scenarios. In scenario 1, energy storage stations achieve profits through peak shaving and frequency modulation, auxiliary services, and delayed device upgrades . In scenario 2, energy storage power station profitability through peak-to-valley price differential arbitrage.
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”.
The system equipment parameters, economic parameters and load parameters are input. When the power consumption is low, the energy storage system will store the electric energy in the heat accumulator and directly supply the heat to the outside with the optimization goal of maximizing the total revenue.
