Wind turbine control is critical in power generation from wind, thus assuring great efficiency and cost-effectiveness. This has been a subject of intense research, and its advancements are critical to developing even better and efficient wind turbines. This research looks at several passive flow control mechanisms for horizontal wind turbines.

Near-surface wind speed (NSWS), a determinant of wind energy, is influenced by both natural and anthropogenic factors. However, the specific impacts of volcanic eruptions on NSWS, remain unexplored. Our simulations spanning the last millennium reveal a consistent 2-year global NSWS reduction following 10 major historical eruptions.

In the anthropocene era, one of the greatest challenges facing trophic modeling applied to the marine environment is its ability to couple the multiple effects of both climate change and local anthropogenic activities, notably the development of offshore wind farms. The major challenge is to create scenarios to characterize their cumulative effects on the functioning of the entire socio-ecological system, in order to propose appropriate management plans. Although modeling cumulative impact on socio-ecological networks is not yet widely used, data reported in the present review article show that the relevance of this approach could be established in the context of offshore wind power.

In wind energy generation systems, ensuring high energy quality is critical but is often compromised due to the limited performance and durability of conventional regulators. To address this, this work presents a novel controller for managing the machine-side inverter of a single-rotor large wind turbine system using an induction machine-type generator. The proposed controller is designed using proportional, integral, and derivative error-based mechanisms, which fundamentally differ from traditional proportional-integral (PI) regulators.

Alpine meadows are vital ecosystems on the Qinghai-Tibet Plateau, significantly contributing to water conservation and climate regulation. This study examines the energy flux patterns and their driving factors in the alpine meadows of the Qilian Mountains, focusing on how the meteorological variables of net radiation (), air temperature, vapor pressure deficit (), wind speed (), and soil water content () influence sensible heat flux () and latent heat flux (). Using the Bowen ratio energy balance method, we monitored energy changes during the growing and non-growing seasons from 2022 to 2023.
