If electricity prices experience wide day-to-day fluctuations, or if you’re a commercial customer subjected to high demand charges, peak shaving can lead to substantial energy cost savings. The higher the demand charges, the higher the potential savings. The size and efficiency of the BESS also matter.
This paper discusses the challenge of optimally utilizing a finite energy storage reserve for peak shaving. The Energy Storage System (ESS) owner aims to reduce the maximum peak load as much as possible while preventing the ESS from being discharged too rapidly (resulting in an undesired power peak).
Energy storage can facilitate both peak shaving and load shifting. For example, a battery energy storage system (BESS) can store energy generated throughout off-peak times and then discharge it during peak times, aiding in both peak shaving (by supplying stored energy at peak periods) and load shifting (by charging at off-peak periods).
Peak shaving refers to the practice of reducing electricity demand during peak hours to prevent overloading the power grid. It can also be used by utilities or renewable energy plants to increase the capacity of the existing grid infrastructure by deferring T&D upgrades into the future, providing a more cost efficient upgrade path for the power system. Fig.1 illustrates the principle of peak shaving, where the area corresponds to power x time, i.e., energy.
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.
One of the main challenges of real-time peak shaving is to determine an appropriate threshold level such that the energy stored in the energy storage system is sufficient during the peak shaving process.
