FAQS about Economic analysis of energy storage peak shaving projects

What is peak shaving in power system?

In the power system, the load usually shows “peak” and “valley” differences. It refers to the fact that the load is higher during certain times of the day and lower during other times of the day. In order to meet the peak demand, the power system needs to carry out peak-shaving.

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 peak shaving?

Peak-shaving refers to the reasonable adjustment of power system according to the change of power load to ensure the reliability and stability of a power supply. In the power system, the load usually shows “peak” and “valley” differences.

Will energy storage become the second largest peak-shaving resource?

By 2030, the scale of energy storage will expand rapidly, becoming the second largest peak-shaving resource in addition to thermal power units, as shown in Table 1.

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 is peak shaving unbalanced?

Due to the cost of deep peaking of conventional units, the system needs a larger charging power provided by ES to participate in peak shaving when the power of RE is larger (e.g. Fig. 7 (Typical day 3 0:00 to 8:00 p.m.)). In this way, the charge and discharge of ES involved in peak shaving may be unbalanced.
