Denormalized Power

In order to estimate the deviation of the performance of a specific inverter, the reference normalized power needs to be denormalized so that the inverter’s capacity is accounted for.

The denormalized power will be clamped so that it does not exceed the inverter’s AC capacity.

This signal requires all inverters at the site to have metadata values set for both AC and DC capacity (set on inverter level).

where

Pdenorm is the denormalized power

CDC is the inverter's DC capacity (metadata field)

av_dc_norm_pow.png

is the average of all site inverters' DC capacity (metadata field)

Pnorm,ref is the reference normalized power
