Peak shaving can help reduce energy costs in cases where peak loads coincide with electricity price peaks. This paper addresses the challenge of utilizing a finite energy storage reserve for peak shaving in an optimal way.
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.

The goal of peak shaving is to avoid the installation of capacity to supply the peak load of highly variable loads. In In cases where peak load coincide with electricity price peaks, peak shaving …
Sometimes called "load shedding," peak shaving is a strategy for avoiding peak demand charges by quickly reducing power consumption during a demand interval. In some cases, peak shaving can be accomplished by switching off equipment with a high energy draw, but it can also be done by utilizing separate power generation equipment, such as on-site …
