According to the invention, a system, in order to determine in a real-time manner the power of a plurality of decentralized technical units, which - are spatially distributed in order to generate and/or store and/or consume electrical energy and which - are connected to a power supply network in order to feed in and/or draw electrical energy and which - are connected to a control center by means of a communication connection in order to control the operation of the technical units, is characterized by - a data memory in the control center, which data memory is designed store a power value or a plurality of different power values for each of the technical units, and by - a trigger signal transmitter for each of the technical units, which is designed, in the case of each state change of the technical unit in question between the power value and zero or between the power value and another of the power values, to send a trigger signal, which signals the state change, to the control center, and by - a computer in the control center, which computer is designed to calculate the instantaneous power of at least one technical unit that is in operation from the stored power values in accordance with the trigger signals. The invention further relates to a corresponding method. |
