When the frequency fluctuates, energy storage stations can swiftly respond to the frequency changes in the power system, offering agile regulation capabilities and maintaining system stability [ 10 ]. Thus, the participation of energy storage stations is also crucial for ensuring the safety and stability of operations in the power system [ 11 ].
where is the rated power configured for the energy-type storage system, is the rated power configured for the hybrid-type storage system, is the rated power configured for the power-type storage system, is the charging coefficient of the energy storage, and is the discharging coefficient of the energy storage.
To leverage the efficacy of different types of energy storage in improving the frequency of the power grid in the frequency regulation of the power system, we scrutinized the capacity allocation of hybrid energy storage power stations when participating in the frequency regulation of the power grid.
The economic effect of energy storage construction has received increasing attention in recent years, as the use of renewable energy sources has grown, and the need for reliable and flexible power systems has become more pressing.
Specifically, referring to the frequency deviations and the limitations of the dead zone, the energy storage system determines its output duration and action magnitude. This control function can be implemented using multiple power conversion systems (PCS) for energy storage.
Overall, the available literature suggests that energy storage construction can have significant economic benefits, including reduced costs of power generation, improved reliability of the power grid, and reduced carbon emissions. However, the existing research has mainly focused on the energy sector in a national or global region.
