Abstract: Aspects of the present invention relate to a method of controlling a renewable energy power plant connected to a power network. The renewable energy power plant comprises one or more renewable energy generators having an active power reserve for supplying additional active power to the power network and an energy storage system having an active power store. In response to detecting a frequency event on the power network a power sequence is implemented to manage the additional active power contributions from the energy storage system and the one or more renewable energy generators to satisfy the active power request.

Abstract: Operating a renewable energy power includes receiving a measurement signal indicative of a measured power characteristic of the plant at a point of connection to a power network; controlling the plant 12) according to a normal mode of operation to provide power by determining and dispatching power set points, the power set points being determined by: acquiring samples of the measurement signal at a sample rate; and determining the power set points based on the sampled measurements and a target level for the measured power characteristic; and monitoring the measurement signal to detect an undersampled oscillation of the measured power characteristic in the sampled measurements, and thereby detecting a control fault; and then controlling the plant according to a fault mode of operation.
