The results show that the method proposed in this article can reasonably plan the capacity of energy storage, improve frequency safety during system operation, and reduce the operating cost of the power grid.
Frequency regulation is critical for maintaining a stable and reliable power grid. When the demand for electricity fluctuates throughout the day, the power grid must be continuously adjusted to ensure a consistent frequency.

The critical role of energy storage in contemporary grid management lies in its capacity to provide both peak load regulation and frequency regulation, which ensures the system operates within acceptable limits.
Grid frequency regulation and peak load regulation refer to the ability of power systems to maintain stable frequencies (typically 50Hz or 60Hz) and balance supply and demand during peak and off-peak periods.
Energy storage (ES) can mitigate the pressure of peak shaving and frequency regulation in power systems with high penetration of renewable energy (RE) caused by uncertainty and inflexibility.
