Energy storage frequency and peak regulation
To explore the application potential of energy storage and promote its integrated application promotion in the power grid, this paper studies the comprehensive application and
The unique advantages of energy storage (ES) (e.g., power transfer characteristics, fast ramp-up capability, non-pollution, etc.) make it an effective means of handling system uncertainty and enhancing system regulation [, , ].
Here, we focused on this subject while conducting our research. The multi-timescale regulation capability of the power system (peak and frequency regulation, etc.) is supported by flexible resources, whose capacity requirements depend on renewable energy sources and load power uncertainty characteristics.
Relationship between the RE penetration, ES power, and confidence in satisfying. 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.
Fitting curves of the demands of energy storage for different penetration of power systems. Table 8. Energy storage demand power and capacity at 90% confidence level.
