Energy storage can facilitate both peak shaving and load shifting. For example, a battery energy storage system (BESS) can store energy generated throughout off-peak times and then discharge it during peak times, aiding in both peak shaving (by supplying stored energy at peak periods) and load shifting (by charging at off-peak

Power plants use three load ranges: Base load: The minimum level of electricity demand required over a period of 24 hours. This load is needed to provide power to components that keep running at all times. Intermediate load: The load from mid-morning until the evening. Peak load: The time of high demand, often for only shorter durations.

In recent years, with the rapid development of the social economy, the gap between the maximum and minimum power requirements in a power grid is growing [1].To balance the peak–valley (off-peak) difference of the load in the system, the power system peak load regulation is utilized through adjustment of the output power

A storage tank in a solar system has several functions the most important of which are: •.
