A comparison of optimal peak clipping and load shifting energy storage

However, to discharge during the peak demand, the energy storage system is charged during off-peak hours (valley filling, or energy price arbitrage) to take advantage of lower utility rates. The LS control strategy, however, charges during off-peak hours and discharges during on-peak hours daily – consistently shifting the power demand to

Flexible Load Participation in Peaking Shaving and Valley Filling

The decreasing proportion of the peak-valley difference between the power grid and users'' electricity purchasing costs are both lower than that in the base case when the load reduces by 20%.
