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.
New energy storage methods based on electrochemistry can not only participate in peak shaving of the power grid but also provide inertia and emergency power support. It is necessary to analyze the planning problem of energy storage from multiple application scenarios, such as peak shaving and emergency frequency regulation. This …
However, a theoretical total energy cost based on the EPEX prices is included in the objective function, as a worst-case measure for shifts in energy procurement cost due to peak shaving. In this manner, the control schemes are prevented from reducing the peak power cost at the expense of energy procurement and grid usage costs.
The line of literatures consider co-optimization of storage starts from [14]. In [14], the authors analyze the economics of using storage device for both energy arbitrage and frequency regulation service. The work in [15] extended this "dual-use" idea by considering
