Peak shaving, or load shedding, is a strategy for eliminating demand spikes by reducing electricity consumption through battery energy storage systems or other means. In this article, we explore what is peak shaving, how it works, its benefits, and intelligent battery energy storage systems.
Index Terms—Distribution grids, energy arbitrage, energy storage systems, peak shaving, stochastic optimization I. INTRODUCTION Energy storage systems (ESSs) is an emerging technology that can be used to compensate the negative effects of the into the
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
The peak-valley characteristic of electrical load brings high cost in power supply coming from the adjustment of generation to maintain the balance between production and demand. Distributed energy storage system (DESS) technology can deal with the challenge very well. However, the number of devices for DESS is much larger than central energy

At present, the research related to EPC has been relatively mature, mainly focusing on the application of EPC [5,6,7], the main influencing factors of EPC [8,9,10,11], and the analysis of the benefits of EPC and its allocation methods [12,13].The literature [5,6,7] focused on the application of EPC in developing countries, and the study showed
To achieve the goal of carbon peak in 2030 and carbon neutral in 2060, one of the main tasks of China''s energy transformation is to build a new type of power system with renewable energy as the main body.

Peak Shaving is one of the Energy Storage applications that has large potential to become important in the future''s smart grid. The goal of peak shaving is to avoid the installation of capacity to supply the peak load of highly variable loads. In cases where peak load coincide with electricity price peaks, peak shaving can also provide a reduction of energy cost.
