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.
Why is energy storage important in grid balancing?
Energy storage technology plays an important role in grid balancing, particularly for peak shaving and load shifting, due to the increasing penetration of renewable energy sources such as solar energy and their inherent intermittency and unpredictability.
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.
Can levelized cost of electricity be used for energy storage applications?
Mostafa et al. and Hunter et al. both adopted the levelized cost of electricity for assessing energy storage applications. Chen et al. evaluated the peak shaving benefits of nuclear and battery systems in terms of the internal rate of return (IRR), payback period (PBP), and levelized cost of electricity (LCOE).
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.
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.
