Abstract: A method of controlling the operation of a power plant is provided. The power plant comprises plural energy systems (110-140) that are individually controllable, the plural energy systems comprising plural renewable energy generating systems (110, 120) of at least one type, wherein the plural energy systems are coupled to a power grid (200) for exchanging electrical power with the power grid (200). The method includes obtaining operating data (40) of at least the renewable energy generating systems (110, 120) of said type, the operating data (40) being at least indicative of a lifetime consumption of the renewable energy generating systems (110, 120); obtaining estimated environmental data that estimates one or more future environmental conditions; and modeling at least one of residual lifetime, energy production, or power demand satisfaction for a power demand from the power grid for the energy systems of the power plant (100). The modeling is based on the obtained operating data (40) and is performed for a future period of time using the estimated environmental data. The modeling considers a modification of operating modes of at least the renewable energy generating systems (110, 120). Based on the modeling, the operation of the power plant (100) is adjusted.

Abstract: A method of operating a wind turbine (100) using a controller (10) is provided. The controller (10) is configured to activate or deactivate each of two or more distinct control features of the wind turbine (100), each control feature changing the operating characteristic of the wind turbine (100) and having an impact on at least one of lifetime and energy production of the wind turbine (100). The method includes determining a type of optimization parameter and an optimization target for the optimization parameter, wherein the optimization parameter is related to at least one of lifetime or energy production of the wind turbine (100). The method further performs one or more optimization steps, wherein each optimization step is performed for a different combination of activation states of the two or more control features. Based on the one or more optimization steps, an optimal combination of activation states of the two or more control features for which the estimated optimization parameter achieves the optimization target is determined.
