Abstract: A power plant control system for a first renewable energy power plant comprising one or more renewable energy generators. The power plant control system comprises receiving means for receiving a power delivery demand from a transmission grid operator; control means configured to control the one or more renewable energy generators of the first renewable energy power plant so as to supply power that targets the received power delivery demand; and communication means configured to transmit a request to one or more further renewable energy power plant control systems to request operation of one or more power compensation units associated with respective ones of the further renewable energy power plants.

Abstract: A method is provided of protecting a wind turbine with a doubly-fed induction generator (DFIG) against a sub-synchronous resonance (SSR) event acting on the wind turbine. A plurality of power-output values or current-output values is measured over a given period of time that corresponds to a measurement cycle. It is determined whether power-output values or current-output-values measured in the at-least-one measurement cycle are indicative of an SSR-event critical for further operation of the wind turbine. The wind turbine is shut down if the measured power-output values or current-output values are indeed indicative of an SSR-event critical for operation of the wind turbine.
