Grid frequency regulation and peak load regulation refer to the ability of power systems to maintain a stable frequency (typically 50Hz or 60Hz) and balance supply-demand during peak and off-peak periods.
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.
Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.
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 [, , ].
However, the demand for ES capacity to enhance the peak shaving and frequency regulation capability of power systems with high penetration of RE has not been clarified at present. In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.
Energy storage demand power and capacity at 90% confidence level. As shown in Fig. 11, the fitted curves corresponding to the four different penetration rates of RE all show that the higher the penetration rate the more to the right the scenario fitting curve is.
In Ref. , an operational cost model for a hybrid energy storage system considering the decay of lithium batteries during their life cycles was proposed to primarily minimize the operational cost and ES capacity, which enables the best matching of the ES and wind power systems.
