Abstract: The invention relates to a method for controlling a wind turbine system, more particular for a method for determining shadow flicker at a location and identifying a wind turbine in a wind park with a plurality of wind turbines causing the shadow flicker. A remote detector located at or near the location is determining the presence of shadow flicker and generating flicker data representative of the shadow flicker. A target wind turbine potentially causing a shadow at the location is identified based on the turbine position and the position of the sun. Operational data from the target wind turbine is obtained and it is verified whether the target wind turbine generates the shadow flicker by comparing the flicker data and the operational data.

Abstract: A method for controlling wind turbines. Incident signal data is obtained from wind turbines and fed to an artificial intelligence (AI) model in order to identify patterns in the incident signals generated by the wind turbines. One or more actions are associated to the identified patterns, based on identified actions performed by the wind turbines in response to the generated incident signals. During operation of the wind turbines, one or more incident signals from one or more wind turbines are detected and compared to patterns identified by the AI model. In the case that the detected incident signal(s) match(es) at least one of the identified patterns, the wind turbine(s) are controlled by performing the action(s) associated with the matching pattern(s).

The one or more instructions are fetched from the queue independent with respect to events initiated externally with respect to the private network.

Abstract: The present disclosure provides a method for obtaining site data from a power plant within a private network of the power plant, where the power plant comprises one or more wind turbine generators. The method comprises a step of providing at an internal computer system placed internally with respect to the private network site data relating to the power plant, where the site data is in a site data format. The site date is stored in the internal computer system, and pushes to an external data interface outside the private network. The site data is transformed to a universal data format being different from the site data format before or after pushing the site data.
