Abstract: A method (S1-S9) is used to assign electrical energy (E) to a group of electrical energy stores (E1-En), in particular a fleet of electric vehicles (E1-En), several of which are intended for bidirectional conduction of current, wherein (a) at least one first instance (INST1), which controls individual load curves of the group of electrical energy stores, forecasts an aggregated load curve (PLG) for these energy stores (S1) and reports said aggregated load curve to a second instance (INST2-1, INST2-2) (S2), (b) the second instance trades an amount of energy corresponding to the forecast load curve (PLG) (S3), (c) the first instance, during the forecast period (T) that has then occurred, forecasts an aggregated load curve band (LGB) for the remaining duration of the forecast period in due consideration of the load curves actually implemented during the forecast period up until then (S4) and reports said aggregated load curve band to the second instance (S5), (d) the second instance determines an optimized load

Abstract: 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.

Abstract: Compounds are used as catalysts according to general formula (1) M+x(C(SO2CF3)3)x, whereby x is equal to 1 or 2; M represents one hydrogen or alkaline metal atom when x equals 1; and M represents one alkaline-earth metal atom when x equals 2. The invention also relates to a novel Mg compound of formula (1).
