Simplified peak billing
The simplified peak billing model is similar to peak billing but uses data from external weather services rather than data measured on-site. It is based on the German "vereinfachte Spitzabrechnung”, but can be applied to any system which meets the prerequisites.
Prerequisites
Irradiation data from an external weather provider
Grid operator's relative active power setpoint value
The derated power must be lower than the expected power
The measured power must be lower than the expected power
