Lost Production to Performance (Inverter)

Lost production to performance is the lost production when Time-Based System Availability (Inverter) is considered Available. This is the opposite of how Lost Production to Downtime works.

Lost Production is the difference between potential production and actual production. It is possible to configure when Time-based System Availability is available.

Technology

Solar

Remarks

To determine if there is any lost production at all we look at the time-based availability. All lost production during a time step will be attributed to performance if the availability is 100%.

This signal does not account for the losses during curtailment.

Unlike Lost Production to Downtime, Lost Production to Performance can have negative values.

Equation

Where:

ELPP

is Lost Production to Performance

ATS

is Time-based System Availability

statusC

is a curtailment status that exists for the timestep

Epotential+

is the potential energy production, clamped to the positive part

Eactual+

is the actual energy production, clamped to the positive part Energy or Power with fallback

Pcp,perf

is the Cascading Potential Power for Performance

T

is the device resolution in hours.

P

is Power

E

is Energy export

Usage Example

In this example, you can see that the potential power is most of the time slightly higher than the actual power AC, so there is some Lost production to performance.
