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
