Lost Production to Curtailment (Inverter)

These calculations calculate lost production due to curtailment, as defined by statuses classified as curtailment for the device.

This covers the following signals:

  • Lost Production to Curtailment (Total) (3228)

  • Lost Production to Curtailment (Grid) (3229)

  • Lost Production to Curtailment (Technical) (3230)

  • Lost Production to Curtailment (Grid Constrain) (3231)

Technology

Solar

Remarks

The matching curtailment statuses used in this calculation will be found based on the selected signal for calculation. For example, the Lost Production to Curtailment (Technical) (3230) signal will only match curtailment statuses with the "Technical curtailment” (108) code. The Lost Production to Curtailment (Total) (3228) signal will look at all inverter curtailment codes.

Where:

ELPC+

is the Lost production to curtailment, clamped to the positive part

statusC

is an active Curtailment status

Eactual+

is the Energy or Power with Fallback, clamped to the positive part

Epotential+

is the potential energy production, clamped to the positive part

Pcp

is Cascading Potential Power - Solar

T

is the device resolution in hours

Usage Example

In this example, the statuses of all 3 possible kinds are created and are active at this data point. This shows that the same value is found in the Lost production signals of all 3 curtailment types, as well as, in the Lost production to Curtailment (Total):
