Quantifying the Variability of Wind Energy

摘要: Wind by its very nature is a variable element. Its variation different on timescales and spatially magnitude can change dramatically depending local climatology terrain. This has implications in variety of sectors, not least the wind energy sector. The accuracy weather forecasting models increased significantly last few decades these are able to give an insight into variability hourly daily timescales. On shorter timescales, predicting chaotic turbulent fluctuations far more challenging. Similarly, ability make seasonal forecasts extremely limited. General circulation (GCMs) insights possible future decadal fluctuations, but there still large uncertainties. Observational data useful information concerning quality spatial coverage be variable. An understanding scale variations important farm siting. In 40 years, have been significant advances using computer models, although remain challenges behavior certain environments. Both temporal considerations when power integrated electricity networks, this will become ever consideration as generation makes increasing contribution our global needs.
