1. A method for feeding electric power into an electric supply network at a network connection point using a wind park including a plurality of wind power installations, comprising:
determining an expected power for a particular feed-in period, the expected power indicating a power value of wind power expected from the wind park in the particular feed-in period, wherein determining the expected power includes:
receiving a weather forecast, wherein the weather forecast includes an associated expected accuracy value,
determining, using the weather forecast, an expected wind speed for the particular feed-in period,
determining an adjusted expected wind speed based on the expected wind speed, local weather data measured in an environment of the wind park, and local operating data of the wind park, and
determining the expected power based on the adjusted expected wind speed;
determining an expected accuracy of the expected power based on the associated expected value of the weather forecast, the expected accuracy of the expected power being an expected measure of accuracy of power reaching the expected power during the particular feed-in period; and
planning a black start and/or network restoration based on the expected power and the expected accuracy of the expected power.
