WindreX — Wind Resource eXchange

A Python library for wind resource assessment, wake modeling, turbine database management, MCDA-based site suitability analysis, and capacity factor computation.

Features

• Weibull Analysis: MLE fitting, PDF, mean power density
• Wind Rose: Directional frequency and speed distributions
• Wind Shear: Power-law extrapolation to hub height
• Wake Modeling: Jensen/Park single-wake deficit, array efficiency with RSS superposition
• Capacity Factor: Hourly CF from Open-Meteo, NASA POWER, or ERA5 data
• Turbine Database: atlite YAML + OEDB REST API
• MCDA: Multi-criteria site suitability (entropy, PCA, manual weights)
• Economics: LCOE, NPV, IRR, sensitivity analysis
• Regional Analysis: Grid-based resource assessment with development zones

Installation

pip install windrex

With ERA5 support:

pip install windrex[era5]

Quick Start

from windrex import fit_weibull, weibull_pdf, compute_wind_rose
import numpy as np

# Fit Weibull to measured speeds
speeds = np.random.weibull(2.0, 10000) * 7.0
k, A = fit_weibull(speeds)
print(f"Weibull k={k:.2f}, A={A:.2f}")

# Compute wind rose
directions = np.random.uniform(0, 360, len(speeds))
rose = compute_wind_rose(speeds, directions)
