Discussions on the Main Electrical Wiring Scheme for a 400 MW Offshore Substation Station

open access: yes南方能源建设, 2019
[Introduction] Offshore wind farms are characterized by long distance from shore, high costs of repair due to vessels involved and weather, long maintenance cycles and the fact that daily operations and maintenance is highly dependent on weather and sea ...

Wind Power Forecasting

open access: yes, 2021
The wind power generation depends on wind speed and its derivatives like: wind speed and direction. With consideration of stochastic nature of wind power, this work addresses three main issues: first, it discusses the state of art of energy forecasting with emphasis on wind power forecasting. It provides an overview of different variables on which wind

Analysis of Wind-Turbine Main Bearing Loads Due to Constant Yaw Misalignments over a 20 Years Timespan

open access: yesEnergies, 2019
The compact design of modern wind farms means that turbines are located in the wake over a certain amount of time. This leads to reduced power and increased loads on the turbine in the wake. Currently, research has been dedicated to reduce or avoid these

Mid-term Scenario Generation for Wind Power Using GAN with Temporal-correlation Enhancement Block [PDF]

open access: yesE3S Web of Conferences, 2020
Under the background of increasing renewable energy penetration and rigid demand for midterm generation planning, the accurate expression of wind power uncertainty becomes more and more important.

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Grid-Connected Adaptive Analysis and Control of the DC Wind Turbine Under the Grid-Side Transient Faults

open access: yesIEEE Access, 2023
The grid-side transient fault ride-through problem seriously affects the stable operation of the grid-connected wind turbine. At present, the grid-connected adaptability analysis of DC wind turbine (DCWT) under the grid-side transient faults is still a ...

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Evaluation of Wear Models for the Wear Calculation of Journal Bearings for Planetary Gears in Wind Turbines

open access: yesLubricants, 2023
To increase the power density of the electromechanical drive train of wind turbines, journal bearings can be used as planetary gear bearings instead of rolling bearings. This technological change presents new challenges.
