A method for controlling at least one controllable system component in an electrical installation, where the installation is connected to an electrical supply network via a network connection. A measurement value of a performance from the supply network is detected for each individual successive time interval, and if one of the measurement values is larger than a predetermined threshold value, the performance is guided below the threshold value by switching electrical compensation power. The measurement value of the current time interval is predicted as a forecast value using a control device at at least one time within the current time interval in question by using forecast data to add a future course of the performance extending to the end of the time interval, and thereby deciding during the time interval how much compensation power is necessary.

A method for aggregating operating values of a plurality of spatially distributed operating units, wherein aggregation times are predefined and the operating values of each operating unit describe an operating variable at each of the respective aggregation times, and a respective aggregation value is generated from time-synchronized operating values of the operating units for the aggregation. Respective raw values are received for each of the operating units, which describe the operating variable at a respective detection time, and the operating values of at least one of the operating units are formed based on the raw values thereof. For each of the aggregation times, and based on a predetermined checking function, a respective operating value is sought which fulfills a synchronization criterion and a plausibility criterion. If an operating value of this type is found it is used, and if no such operating value is found, a detection gap is signaled.

A method for operating a plurality of technical units as a pool on an electric distribution network. A central controller is used to receive flexibility data from each technical unit. The flexibility data is used by the unit to indicate a power interval within which the electric power of the unit is allowed to vary or varies in an expected manner. Depending on a specified optimization target of the pool, an individual non-binding stimulus function is ascertained for each unit from the flexibility data of each unit and is provided to the respective unit. In response to the individual stimulus function, a respective schedule which describes a time curve of the power exchange planned according to a local optimization target of the unit is then received from each unit, and an overall schedule for the pool is generated from the schedules of the units.
