摘要

A method for computer-assisted determination of the usage of electrical energy produced by a power generation plant, particularly a renewable power generation plant;The invention relates to a method for computer-assisted determination of the usage of electrical energy produced by a power generation plant, particularly a renewable power generation plant. The method uses a plurality of neural networks (NN1, NN2) having a different structure or being learned differently for calculating future energy amounts produced by a power generation plant. To do so, the energy outputs of the power generation plant forecasted by the plurality of the neural networks (NN1, NN2) are used to build histograms. Based on those histograms, energy amounts for different confidence levels describing the likelihood of the availability of the energy amount are determined and different uses are assigned to different energy amounts. Particularly, energy amounts having a higher likelihood of availability in the future are sold at higher prices than other energy amounts. The method of the invention is preferably used for renewable power generation plants for which the energy output is fluctuating according to environmental conditions. E.g., the invention may be used for a wind power generation plant or a solar power generation plant.
