The invention relates to a rolling correction method based on current generated power forecasting for an output lower limit of a new energy field station. The method aims at adapting to the situationthat for the new energy field station, historical year-on-year meteorological resources are very different, and a power grid does not have an effective mechanism for distinguishing components of dailypower generation quantity. According to the rolling correction method based on current generated power forecasting for the output lower limit of the new energy field station, an effective mechanism adapting to the situation is given. After the condition is taken in to account that the new energy field station directly supplies power to users with large consumption, on the premise that the power grid runs safely, the new energy field station needs to ensure reasonable basic power generation quantity to meet the electric quantity for participating in direct power supply to the users with the large consumption.
