Patent number: 11828268Abstract: The invention relates to a method for determining the energy production to be expected for a wind power installation for a forecast time period, which may be an expected annual energy production. The installation has installation components. In the method, at least one of the installation components is selected as a thermally relevant component and chronologically distributed wind speed values are specified for the forecast time period. An expected power output level of the installation is determined for one of the wind speed values. In the power output level determining step, a component temperature which is assigned to this wind speed value is taken into account by the at least one thermally relevant component. The expected power output level of the installation, which is determined for the wind speed value, is used to determine the energy production of the installation which is to be expected for the forecast time period.Type: GrantFiled: December 18, 2020Date of Patent: November 28, 2023Assignee: Wobben Properties GmbHInventors: Hussam Daboul, Kai Enskonatus, Muhanad Mahmoud
