Interface server with virtual objects for mapping of measuring and / or control devices

The invention relates to a system for determining and / or controlling the supply of power to at least one delivery point of a supply network with at least one real measurement and / or control device, wherein the at least one delivery point is configured to decrease a supply power of at least, and wherein the at least one real measurement - and / or control device may provide data for a data network. The object underlying the invention is to provide a system which can be flexibly adapted to the requirements of new delivery models in supply networks. This object is achieved by at least one interface server, which provides at least one functional, virtual object, the i. several real measurement and / or control devices and / or one or more other functional, virtual objects of the same or a different interface server, where multiple real measurement and / or control devices are associated, and ii. one or more characteristics of its associated real measurement and / or control devices can be assigned, and which has at least a first internal interface and a second, external interface, wherein the virtual object on the first internal interface with its associated real measurement and / or control devices or virtual objects can exchange data and wherein the may exchange virtual object on the second, external interface data with the data network that are correlated with the data received from the real measurement and / or control devices and / or other virtual objects, data or to control the real measurement and / or control means are determined, and wherein the interface server and / or at least one of the virtual objects are arranged to detect data on the structure of its associated real measurement and / or control devices or its associated further virtual objects along with their associated real measurement and / or control devices, and to the data network to pass on to can.
