Abstract: An off-grid wind turbine system comprising a wind turbine with an electric generator for generating an initial electric power output. An electrolyzer system with a hydrogen electrolyzer located inside the nacelle or tower of the wind turbine, so as to generate hydrogen by an electrolysis process. An electric converter system serves to convert the initial electric power output into a DC electric power output dedicated for powering the electrolyzer. The produced hydrogen is stored in a hydrogen storage tank.

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.
