Method for generating a performance forecast and forecasting device

摘要

The invention relates to a method for generating a power forecast for at least one regenerative generating plant (30.1, 30.2, 30.3), comprising providing at least one set of meteorological forecast parameters for at least one installation site of at least one regenerative generating plant (30.1, 30.2, 30.3), and generating a performance forecast for the regenerative generating plant (30.1, 30.2, 30.3) at least based on the set of meteorological forecast parameters, wherein the provided set of meteorological forecast parameters is compared with at least one historical set of meteorological forecast parameters in a comparison step, wherein in a database (14) a plurality of historical sets of meteorological forecast parameters are respectively stored together with associated historical actual data sets of the regenerative generation plant (30.1, 30.2, 30.3), at least one historical actual data record of the re generative generating plant (30.1, 30.2, 30.3) is determined based on the comparison result, and the power forecast for the regenerative generating plant (30.1, 30.2, 30.3) is generated at least in dependence on the specific historical actual data record.
