In the event of a deviation of the present charging current curve from the stored charging current curves at the plurality of charging stations which is greater than a threshold, a signal is output.

Abstract: A method performed in which a forecast, a generation information, and a regulation information are obtained. A control information is determined in the event that the regulation information is indicative of over- or underproduction. The control information is indicative of a control of the amount of electrical energy generated by power generating plants.

Operating points for the plants are determined such that, for the remaining time, the amount of energy generated by the plants for the predetermined interval saves or generates at least one determined difference between the amount of energy generated according to the forecast and generation information. The operating points are based on the control information. The determined control information is output.
