6 FAQs about [Energy storage participates in deep peak load regulation]

Does es capacity enhance peak shaving and frequency regulation capacity?

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.

What is the power and capacity of Es peaking demand?

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.

What is the multi-timescale regulation capability of a power system?

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.

How does energy storage power correction affect es capacity?

Energy storage power correction During peaking, ES will continuously absorb or release a large amount of electric energy. The impact of the ESED on the determination of ES capacity is more obvious. Based on this feature, we established the ES peaking power correction model with the objective of minimizing the ESED and OCGR.

Why does es need a larger discharge power?

Due to the limitations of the maximum power of conventional units, the system needs a larger discharge power provided by ES to participate in peak shaving when the power of RE is small (e.g. Fig. 7 (Typical day 2 12:00 to 20:00 p.m.)).

Does penetration rate affect energy storage demand power and capacity?

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.
