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.

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.

What is peak shaving?

Peak shaving is a process of shaving the peak load and filling the load valley. It shifts some of the current or load from the peak period to off-peak period and decreases the net ohmic losses ( Saboori and Abdi, 2013, Shaw et al., 2009, Nourai et al., 2008 ).
