摘要： In order to determine a power output by a first energy producer, wherein the first energy producer is coupled to a second energy producer, a first soft sensor which is trained to determine an individual mode power value of the first energy producer is queried. In a mode combining the first and second energy producers, an individual mode power value determined for the first energy producer by the first soft sensor is read in here. Furthermore, a second soft sensor determines a first power value for the first energy producer and a second power value for the second energy producer. In addition, a total power of the energy producers is determined.
