Peak shaving refers to reducing electricity demand during peak hours, while valley filling means utilizing low-demand periods to charge storage systems. Together, they optimize energy consumption and reduce costs.

If peak shaving is defense, valley filling is offense. One prevents cost spikes; the other optimizes savings. Buy low, sell (or save) high.

Due to the fast charging and discharging characteristics of battery energy storage system, it is charged during low load periods and discharged during peak load periods, thereby shaving and filling the power load of isolated microgrids, alleviating the power.
