Gradient-based wind farm layout optimization with inclusion and exclusion zones [PDF]
Wind Energy ScienceWind farm layout optimization is usually subjected to boundary constraints of irregular shapes. The analytical expressions of these shapes are rarely available, and, consequently, it can be challenging to include them in the mathematical formulation of ...

Probabilistic computation of wind farm power generation based on wind turbine dynamic modeling [PDF]
Dans Proceedings of the 10th International Conference on
Probabilistic Methods Applied to Power Systems - PMAPS 2008, Porto Rico
(2008), 2008 This paper addresses the problem of predicting a wind farm's power generation when no or few statistical data is available. The study is based on a time-series wind speed model and on a simple dynamic model of a DFIG wind turbine including cut-off and cut-in behaviours.

Wind power prediction based on variational mode decomposition multi-frequency combinations
Journal of Modern Power Systems and Clean Energy, 2018 Because of the uncertainty and randomness of wind speed, wind power has characteristics such as nonlinearity and multiple frequencies. Accurate prediction of wind power is one effective means of improving wind power integration.

Turbine location-aware multi-decadal wind power predictions for Germany using CMIP6 [PDF]
arXivClimate change will impact wind and therefore wind power generation with largely unknown effect and magnitude. Climate models can provide insights and should be used for long-term power planning. In this work we use Gaussian processes to predict power output given wind speeds from a global climate model and compare the aggregated predictions to actual ...
