Abstract: Disclosed is a method, performed by an electronic device, for controlling operation of a wind turbine. The method comprises obtaining wind turbine data associated with the wind turbine. The wind turbine data is indicative of conditions of operation of the wind turbine. The method comprises predicting an amplitude modulation (AM) noise parameter indicative of AM noise within a region at a distance from the wind turbine by applying a machine learning model to the wind turbine data. The method comprises generating, based on the AM noise parameter, control data indicative of a control operation of the wind turbine. The method comprises providing the control data to a controller for controlling the wind turbine in accordance with the control data.

Abstract: Aspects of the present invention relate to a method of controlling a renewable power plant comprising a plurality of renewable power generators electrically connected by a local network and configured to supply active power to a main network. The method comprises: in response to receiving a signal requesting substantially zero active power supply to the main network: categorizing a generator as power-supplying, and the remaining generators as power-consuming; operating the power-consuming generators to generate no active power and to have their auxiliary systems draw power from the local network; and operating the power-supplying generator to supply active power to the local network such that the plant supplies substantially zero active power to the main network.

Abstract: A process is provided for making filled mineral fiber products which comprises applying mineral melt to a rotating fiberizing rotor and thereby throwing from the rotor as fibers and forming a substantially annular cloud of fibers, spraying binder into the annular cloud of fibers, carrying the fibers axially from the rotor towards a collector surface and collecting the fibers on the collector surface as a web. The process includes spraying into the substantially annular cloud a slurry which has specific gravity of at least 1.1, preferably at least 1.2, and which comprises a substantially stable liquid dispersion of particulate material in an aqueous binder.

Abstract: A mineral fibre containing plant growing medium comprising lignite has ion exchange capacity and improved water retention properties and does not require disinfection before use.
