Vanika et al. (2023) comprehensively analyzed the direct and indirect value of energy storage in the power system, and established a multiple value evaluation model for energy storage applied simultaneously in peak shaving and valley filling, smoothing renewable energy, and improving power supply reliability.
Due to the important application value of grid side energy storage power stations in power grid frequency regulation, voltage regulation, black start, accident emergency, and other aspects, attention needs to be paid to the different characteristics of energy storage when applied to the above different situations.
Due to factors such as high prices of energy storage devices and imperfect market models, China's grid side energy storage projects are currently in their early stages, with limited engineering applications and a lack of evaluation methods of the actual operational effectiveness of power stations from multiple perspectives.
For each typical application scenario, evaluation indicators reflecting energy storage characteristics will be proposed to form an evaluation system that can comprehensively evaluate the operation effects of various functions of energy storage power stations in the actual operation of the power grid.
To fully utilize the peak function of the energy storage power stations, constant power rate mode is used during charging and discharging, and larger power is used during discharging).
Energy storage is one of the key technologies supporting the operation of future power energy systems. The practical engineering applications of large-scale energy storage power stations are increasing, and evaluating their actual operation effects is of great significance.
