However, according to the current policy of regulatory pricing, particularly the "Opinions on Further Improving the Price Formation Mechanism for Pumped Storage Energy", the capacity tariff for grid-side energy storage stations essentially functions as an equal annual payment mechanism for initial investment recovery.
Energy storage operators act as followers, making decisions regarding storage capacity and operational strategies based on the tariffs set by the grid. Their decision-making process incorporates historical capacity tariffs, operating costs, expected returns, and market dynamics.
Therefore, it is necessary to use the capacity tariff mechanism to ensure that the basic income of the energy storage power station is conducive to the operation and survival of the development of energy storage in China at this stage. The Chinese government has proposed implementing a capacity tariff for grid-side energy storage.
Charge and discharge power and state of charge of the grid-side energy storage. According to Fig. 7, it can be seen that the grid-side energy storage chooses to charge at the time of low and flat electricity prices and discharge at the time of peak electricity prices.
Several studies have shown that a well-designed capacity tariff mechanism can effectively incentivize the development and optimized operation of energy storage stations, thereby enhancing the flexibility and reliability of the power system (Huang et al., 2023; Khalilpour and Lusis, 2020; Varghese and Sioshansi, 2020; Zhang et al., 2023).
Incorporating the energy storage system has demonstrated significant impacts on power system operation, effectively regulating the power supply-demand balance while enhancing both system stability and operational efficiency. Fig. 8. Comparison of the net load curve.
