An integrated fault diagnosis and prognosis approach for predictive maintenance of wind turbine bearing with limited samples
TL;DR: The integrated fault diagnosis and prognosis approach is validated using bearing lifetime test data acquired from a wind turbine in field, and the performance comparison with typical data driven technique outlines the significance of the presented method.
Journal ArticleDOI
Climate change impacts on wind power generation
TL;DR: In this paper, the authors describe the factors that dictate the wind resource magnitude and variability and illustrate the tools and techniques that are being used to make projections of wind resources and wind turbine operating conditions.
Journal ArticleDOI
Improving the flexibility of coal-fired power generators: Impact on the composition of a cost-optimal electricity system
TL;DR: In this article, the authors investigated the impacts of measures designed to increase the competitiveness of coal-fired power plants in future energy systems, which are facing restrictions related to CO2 emissions and variable operation as a consequence of high penetration levels of wind and solar power.
Journal ArticleDOI
A comparison of variation management strategies for wind power integration in different electricity system contexts
Lisa Göransson,Filip Johnsson +1 more
TL;DR: In this article, the authors introduce a new, functionality-based, categorization of variation management strategies: shifting (e.g., batteries), absorbing (eg, power-to-gas), and complementing (dispatchable generation, including reservoir hydropower) strategies.
Journal ArticleDOI
Assessing the Global Wind Atlas and local measurements for bias correction of wind power generation simulated from MERRA-2 in Brazil
TL;DR: In this paper, the authors evaluate different methods for wind power simulation on four spatial resolution levels from wind park to national level in Brazil and show that the global information derived from the GWA can compete with locally measured wind speed data as a source of bias correction.

TL;DR: The Modern-Era Retrospective Analysis for Research and Applications (MERRA) was undertaken by NASA's Global Modeling and Assimilation Office with two primary objectives: to place observations from NASA's Earth Observing System satellites into a climate context and to improve upon the hydrologic cycle represented in earlier generations of reanalyses as mentioned in this paper.
