A method for the communication of system control units (15 to 18) with a plurality of spatially distributed energy generating systems (7 to 11), which jointly feed into a continuous supply network for electrical energy, - wherein request data from the system control units (15 to 18) and system data from the energy generating systems (7 to 11) are received at a common gateway; - wherein the system data are managed in the gateway and the request data are processed in the gateway, and - wherein the gateway sends control commands to the energy generating systems (7 to 11) and/or data responses to the system control units (15 to 18) that result from the processing of the request data, characterized - in that the request data in at least two different data models (33 to 35) of the individual system control units (15 to 18) and/or the system data in at least two different data models (33 to 35) of the individual energy generating systems (7 to 11) are received at the gateway, - in that the request data and the system data are translated from their respective data models (33 to 35) into a metadata model in the gateway, - in that the translated system data are managed in the gateway and the translated request data are processed in the gateway, wherefrom data responses compiled from system data to specific system control units (15 to 18) and/or control commands to specific energy generating systems (7 to 11) result in the metadata model, - in that the data responses and/or control commands are translated from the metadata model into the data models (33 to 35) of the specific system control units (15 to 18) and/or energy generating systems (7 to 11) in the gateway, and - in that the translated data responses and/or control commands are transmitted by the gateway to the specific system control units (15 to 18) and/or energy generating systems (7 to 11). - wherein request data from the system control units (15 to 18) and system data from the energy generating systems (7 to 11) are received at a common gateway; - wherein the system data are managed in the gateway and the request data are processed in the gateway, and - wherein the gateway sends control commands to the energy generating systems (7 to 11) and/or data responses to the system control units (15 to 18) that result from the processing of the request data, - in that the request data in at least two different data models (33 to 35) of the individual system control units (15 to 18) and/or the system data in at least two different data models (33 to 35) of the individual energy generating systems (7 to 11) are received at the gateway, - in that the request data and the system data are translated from their respective data models (33 to 35) into a metadata model in the gateway, - in that the translated system data are managed in the gateway and the translated request data are processed in the gateway, wherefrom data responses compiled from system data to specific system control units (15 to 18) and/or control commands to specific energy generating systems (7 to 11) result in the metadata model, - in that the data responses and/or control commands are translated from the metadata model into the data models (33 to 35) of the specific system control units (15 to 18) and/or energy generating systems (7 to 11) in the gateway, and - in that the translated data responses and/or control commands are transmitted by the gateway to the specific system control units (15 to 18) and/or energy generating systems (7 to 11).
