Weibull Distribution Wind Resource Assessment
Research Guide
What is Weibull Distribution Wind Resource Assessment?
Weibull Distribution Wind Resource Assessment applies the two-parameter Weibull probability distribution to model wind speed variability for wind energy site selection and production forecasting.
Researchers use Weibull parameters k (shape) and c (scale) to characterize wind regimes from measured data. Common estimation methods include method of moments (MOM), maximum likelihood (MLE), and graphical methods (GM). Over 300 papers cite Islam et al. (2011) for Weibull-based potential assessments in Malaysia.
Why It Matters
Weibull modeling enables accurate estimation of wind power density and capacity factors critical for project feasibility (Islam et al., 2011; 300 citations). Azad et al. (2014; 202 citations) diagnose seven Weibull methods, showing MOM and energy pattern factor outperform others for agricultural sites. Errors in Weibull parameters propagate to AEP underpredictions by 10-20% in complex terrain (Herbert-Acero et al., 2014; 304 citations), impacting $B investments.
Key Research Challenges
Parameter Estimation Accuracy
Selecting optimal Weibull parameters from short-term data leads to biased scale c and shape k values. Azad et al. (2014) test seven methods, finding graphical method (GM) inconsistent at low altitudes. Hybrid approaches like ANFIS improve fits but require validation (Mohandes et al., 2011).
Complex Terrain Modeling
Weibull assumes horizontal homogeneity, failing in hilly sites where wakes distort speeds. Politis et al. (2011) use CFD to model wakes, revealing 15-25% power losses ignored by standard Weibull. Coupling with log-law profiles adds uncertainty (Iqbal et al., 2019).
Climate Change Projections
Future wind regimes alter Weibull parameters under RCP scenarios. Tobin et al. (2016) project mid-century reductions in European wind power potential using EURO-CORDEX data. Static Weibull fits from historical data underestimate variability shifts.
