Abstract

The exemplary illustrations generally include a method for controlling and regulating an internal combustion engine-generator system 1000 with a plurality of internal combustion engine-generator units 400 generating electric power which can be connected to a distribution grid and load consumers 200 consuming electric power, with a unit 400 comprising an internal combustion engine 401, 402, 404-408 with variable engine speeds and a generator 421-428, characterized in the steps: determining a given operating state Z* of the internal combustion engine 401, 402, 404-408 of at least one internal combustion engine-generator unit 400; deducting a range of operating states ZB* describing an electric load override Ladm depending on the given operating state Z* for the internal combustion engine of at least one internal combustion engine-generator unit 400, with the determination of the given operating state Z* and the deduction of the range of operating range ZB* occurring based on the calculation model 504 for the internal combustion engines 401, 402, 404-408; providing a scope of load requirements describing potential load requirements of a plurality of load consumers 200.
