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

Section snippets Method statement. Energy storage systems are used for peak load shaving and load leveling. According to Fig. 3, P L (t), which is the load demand at any time, t, must be supplied by the power system.
