Abstract

A method of controlling plural wind turbines is provided, wherein each wind turbine is operable in different operating modes, wherein operating parameters and/or operating features are set differently in the different operating modes. For at least a first of the plural wind turbines, at least some of the different operating modes have a different impact on a residual lifetime of at least a second of the plural wind turbines. In embodiments, the method includes providing at least one candidate operating scheme and estimating a residual lifetime and/or at least one optimization parameter. Estimating of the residual lifetime and/or the optimization parameter considers the impact of the operating mode of the first wind turbine specified in the candidate operating scheme on the residual lifetime of the second wind turbine. The plural wind turbines are then operated in accordance with an operating scheme selected from the candidate operating schemes.
