A method of controlling and/or regulating the amount of electrical energy generated by one or more power generation systems performed by one or more devices, comprising: - obtaining a forecast information indicative of an amount of electrical energy to be generated by one or more power generating plants within a predetermined interval; - obtaining a generation information indicative of an amount of electrical energy generated by the one or more power generating plants, wherein said amount of generated electrical energy to said amount of electrical energy generated by said one or more power generating plants within said predetermined interval and/or is directly predicted for said predetermined interval; - obtaining a regulation information indicative of over- or underproduction of electrical energy generated by the one or more power generating plants for a given time within the predetermined interval in the event that the predetermined interval has not yet expired and the amount of electrical energy to be generated according to the forecast information has already been generated, and vice versa; - determining a control information in the event that the regulation information is indicative of over- or underproduction, wherein the control information is indicative of a control and/or regulation of the amount of electrical energy generated by the one or more power generating plants, wherein the determining of the control information is at least partially based on the obtained regulation information and on the obtained generation information, wherein based on the determined time at which the regulation information is obtained, the remaining time of the predetermined interval is determined, wherein one or more operating points for the one or more power generating plants are determined such that for the remaining time of the predetermined interval, the amount of electrical energy generated by the one or more power generating plants for the predetermined interval saves or generates at least one determined difference between the amount of electrical energy generated according to the forecast information and according to the generation information, and wherein said determined one or more operating points are comprised by the control information, and wherein, based on the one or more operating points for controlling and/or regulating the one or more power generating plants, one or more control parameters for the one or more power generating plants are determined, which set the one or more power generating plants to the one or more operating points; and - outputting or causing the outputting of the determined control information, wherein, based on the determined control information, a control and/or regulation of the one or more power generating plants is carried out. - obtaining a forecast information indicative of an amount of electrical energy to be generated by one or more power generating plants within a predetermined interval; - obtaining a generation information indicative of an amount of electrical energy generated by the one or more power generating plants, wherein said amount of generated electrical energy to said amount of electrical energy generated by said one or more power generating plants within said predetermined interval and/or is directly predicted for said predetermined interval; - obtaining a regulation information indicative of over- or underproduction of electrical energy generated by the one or more power generating plants for a given time within the predetermined interval in the event that the predetermined interval has not yet expired and the amount of electrical energy to be generated according to the forecast information has already been generated, and vice versa; - determining a control information in the event that the regulation information is indicative of over- or underproduction, wherein the control information is indicative of a control and/or regulation of the amount of electrical energy generated by the one or more power generating plants, wherein the determining of the control information is at least partially based on the obtained regulation information and on the obtained generation information, wherein based on the determined time at which the regulation information is obtained, the remaining time of the predetermined interval is determined, wherein one or more operating points for the one or more power generating plants are determined such that for the remaining time of the predetermined interval, the amount of electrical energy generated by the one or more power generating plants for the predetermined interval saves or generates at least one determined difference between the amount of electrical energy generated according to the forecast information and according to the generation information, and wherein said determined one or more operating points are comprised by the control information, and wherein, based on the one or more operating points for controlling and/or regulating the one or more power generating plants, one or more control parameters for the one or more power generating plants are determined, which set the one or more power generating plants to the one or more operating points; and - outputting or causing the outputting of the determined control information, wherein, based on the determined control information, a control and/or regulation of the one or more power generating plants is carried out.
