In this context, this study provides an approach to analyzing the ES demand capacity for peak shaving and frequency regulation.
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.
