Peak-Shaving-unabhängige Energiespeicherung

Peak Shaving ist in einem besonderen Maße für Industrieunternehmen und große Gewerbebetriebe von Bedeutung, da diese in der Regel hohe Leistungen benötigen und einen erheblichen Einfluss auf die Spitzenlasten im Netz haben. Der Einsatz von Peak Shaving-Strategien ermöglicht diesen Betrieben, ihre Energiekosten zu senken und vor allem das

Does peak shaving reduce loss in energy storage?

Loss minimization through peak shaving depends on the number of peak shits ( i.e., storage units) on optimal locations. The robust optimization algorithm i.e., GWO provides significant loss minimization through peak shaving with ES. This paper presents optimal location methodology for energy storage in presence of renewable DG i.e ., wind DG.

How do you calculate peak shaving power?

The total expected wind power PW at any time interval can be obtained as, (5) P W = ∫ 0 ∞ Po w f w v d v The minimum battery size required for peak shaving can be calculated when the desired peak shaving power is decided. Power peaks on the load curves are the area above the reference value Pref.

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 ).

Does peak shaving reduce energy loss in a 34-bus test system?

The results are compared with the well-known genetic algorithm. The proposed methodology is illustrated by various case studies on a 34-bus test system. Significant loss minimization is obtained by optimal location of multiple energy storage units through peak shaving.

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.

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.
