A method operates a technical or non-technical system. At least one information element of a first type which relates to the system and is dependent on the respective system state of the system is transmitted according to the method from at least one first facility of the system to at least one second facility. The second facility uses at least one information element of a second type which originates neither from the first facility nor from a different facility of the system, i.e. it comes from a source other than the system, to estimate the system state, checks, on the basis of the estimated system state, whether the received information matches the estimated system state to a predefined extent, and, in the event of a match to the predefined extent, regards the information as trusted, and otherwise generates a warning signal indicating a possible data attack.

Method for operating a technical or non-technical system, and facility for such systems

The present disclosure relates to charging energy stores, for example for charging electrical vehicle batteries. Various embodiments may include methods for controlling charging operations. For example a method for controlling charging operations of a plurality of electric vehicles may include: analyzing a data record including arrival times, departure times, and charging energies of the plurality of electric vehicles during a first time period; determining an upper limit for charging power based on the data record, the determined upper limit for charging power defined by an amount of power required to charge each electric vehicle between its respective arrival time and departure time; and charging the electric vehicles without exceeding the determined upper limit for charging power during a second time period following the first time period.

Method for controlling charging operations

Systems and methods for probability forecasts and an energy transmission and/or energy distribution network are provided. Operational management may be carried out using a network control system with systematic consideration of forecast uncertainties. The probability of a distribution network being operable in a stable manner (e.g., with N-1 certainty) in a planning period is included. The system includes a forecaster for forecasts for a planning period, a forecast analyzer connected to the forecasts from the at least one forecaster, and elements for further information for outputting estimated forecast uncertainties. The system also includes a stability probability analyzer connected to the forecasts from the at least one forecaster, the estimated forecast uncertainties from the forecast analyzer, and elements for further information for outputting at least one item of information relating to an N-1 stability of the distribution network in the planning period.
