Abstract: The invention provides a method for controlling a wind power plant that receive operating command requests via a distributed system comprising a plurality of subsystems each associated with a respective party capable of issuing requests. One subsystem generates a request to operate the wind power plant in accordance with a defined operating command desired by the associated party. The request is broadcast to each of the other subsystems to approve or disapprove the requests. Each subsystem broadcasts to the other subsystems if it approves the request, and each subsystem maintains a database including a record of which subsystems have approved the request. The wind power plant is controlled based on which subsystems have approved the request, where at least one subsystem other than the subsystem that generates the request needs to have approved the request before the plant implements the defined operating command.

Abstract: Techniques for authenticating and authorising authorizing user access to a component of a power plant within a private network of a renewable power plant having wind turbine generators. One technique includes providing at a local computer system in the private network a list of credentials and authorizations representing a plurality of identifiers and authenticators of users and corresponding access authorizations. The local computer is in direct communication with components of the power plant and is configured to receive a request for access from a user via a computer interface in the component in the private network.

Abstract: Obtaining within a private network of a power plant one or more instructions for controlling the power plant, wherein the power plant includes one or more wind turbine generators, and wherein one or more instructions for controlling the power plant are received at an external digital storage device placed externally with respect to the private network. The one or more instructions are stored in a queue in the external digital storage device. The one or more instructions are fetched from the queue independent with respect to events initiated externally with respect to the private network.

Abstract: A method, controller, wind turbine, and computer program product are disclosed for processing and analyzing wind turbine operational data in a distributed data analysis system. An example method generally includes obtaining, at a first data analysis system, operational data from a plurality of wind turbines in a first wind power plant, determining adjustments to wind turbine operational parameters based on the operational data, pushing the adjustments to the first wind power plant, transmitting the operational data to a second data analysis system not located at the first wind power plant, and transmitting the operational data from the first wind power plant and at least a second wind power plant to a third data analysis system, wherein the third data analysis system comprises a global data analysis system.
