Discharge the energy storage element

How does a storage element discharge?

The STORAGE element discharges for positive values and charges for negative values. Charging and discharging are proportional to the kWrated property. This is illustrated in Figure 3. The Discharge Cycle is set to nominally follow the shape of the daily peak that occurs approximately 5 PM. If you had a 1000 kWh battery with a 250 kW inverter.

What is a storage element?

The storage element is essentially a generator that can be dispatched to either produce power (discharge) or consume power (charge) within its power rating and its stored energy capacity. The model was developed from the Generator element model.

When does the storage element take charge?

The Storage element will only take charge when the kWhStored value is less than kWhRated. You can specify the rate of discharge with the %Discharge value and the rate of charge with the %Charge value. However, the strength of the model is in time-varying simulation modes. Daily, Yearly, and DutyCycle modes are supported.

Why does the storage element attempt to charge if the load drops?

At this time, the Storage element will attempt to charge even if the load has not dropped below the ChargeTrigger value. This is a strategy for ensuring that the Storage element is always fully charged for the next day’s peak load. Figure 3. Illustrating Default Dispatch The default mode is illustrated in Figure 2.

What is a storage element state?

The element discharges for positive values and charges for negative values. The loadshapes are based on the kW and kvar values in the most recent definition of kW and PF or kW and kvar properties. In EXTERNAL mode, Storage element state is controlled by an external Storage controller.

What is a minimum energy discharge level?

Percent of rated kWh storage capacity to be held in reserve for normal operation. Default = 20. This is treated as the minimum energy discharge level unless there is an emergency. For emergency operation set this property lower. Cannot be less than zero. Present amount of energy stored, % of rated kWh. Default is 100%.
