While energy is an essential ingredient for human society, sustainable energy generation, in particular, is becoming increasingly important. Wind energy has been shown to be a suitable candidate to handle the task. However, to keep wind power competitive with other sources of energy, the availability, reliability, and lifetime of turbines will all need to be improved. Real-time monitoring will be able to aid operators, as well as business economics, to make educated operation and maintenance decisions online. This Special Issue aims to provide a platform for academic and industrial contributions to disseminate recent results, and emerging and novel research directions within monitoring and control of wind turbines and wind turbine systems. Research topics include but are not limited to condition monitoring techniques, diagnostics, and prognostic techniques for wind turbine systems and components, resilient control and management of wind turbines, including fault tolerance control, and remaining useful lifetime prediction and extension at component and system level. Contributions to this Special Issue should pay attention to the real-time aspect of the aforementioned topics.
