Abstract: A method for controlling a renewable energy farm (1) comprising a plurality of wind turbines (2) and at least one central control unit (5) is disclosed. The wind turbines (2) of the renewable energy farm (1) are connected to a power grid (3). The central control unit (5) receives a request for change in operation of at least one of the wind turbines (2), where execution of the change in operation causes a change in power output of the wind turbine (2). The central control unit (5) checks whether or not the change in power output is in conflict with at least one obligation of the renewable energy farm (1) towards the power grid (3). In the case that the change in power output is in conflict with at least one obligation of the renewable energy farm (1) towards the power grid (3), execution of the change in operation is deferred.

Abstract: A method for real-time prediction of wind conditions across a wind farm (1) comprising a plurality of wind turbines (1), the wind farm (1) being arranged at a wind farm site, is disclosed. A first library (9) of site specific mean wind flow patterns related to the wind farm site, and a second library (10) of non-site specific turbulence patterns, are provided. Weather data is measured at a plurality of positions within the wind farm site, and based on the measured weather data, a mean wind flow pattern is selected based on the first library (9) and a turbulence pattern is selected based on the second library (10). A site specific wind flow field across the wind farm site is modelled, based on the selected mean wind flow pattern and the selected turbulence pattern, and wind conditions across the wind farm (1) are predicted, based on the site specific wind flow field.
