Peak Load and Base Load defined. Base load is the minimum level of electricity demand required over a period of 24 hours. It is needed to provide power to components that keep running at all times (also referred as continuous load ). Peak load is the time of high demand. These peaking demands are often for only shorter durations.

These plans take the number of utilization hours as the default value, but the type of load for the different power resources (that is, baseload or peak load) is not taken into account in the model. For power supply planning, many recent studies have used the screening curve method (SCM), which can be linked to the actual load curve.

The application of large-scale electricity storage technology is similar to the peak-shaving effect of pumped storage. When the wind power output is large and the electric load is low, the battery is charged,and when the electric load is high, the battery is discharged. At the same time, the configuration of large-capacity heat storage ...

Energy storage can be used to shift the peak generation from the PV system to be used when the demand requires it, as shown in Figure 3. Excess energy can be stored during peak PV generation. This allows for the distribution of this energy when the PV system is not generating adequate power, or not generating at all.
