Wind Energy Estimator

Annual Energy Production (AEP) estimator for wind turbines. Uses a Rayleigh wind-speed distribution integrated against a cubic power curve between cut-in and rated wind speed per IEC 61400-12-1 / NREL methodology. Inputs in metric (m/s, m, kW) by design; outputs AEP (MWh/yr), capacity factor (%), and energy density per swept area (kWh/m²).

Method: Rayleigh PDF f(v) = (π/2) · (v / v̅²) · exp(−π/4 · (v/v̅)²). Cubic power curve: P(v) = P_rated · (v³ − v_ci³) / (v_r³ − v_ci³) for v_ci ≤ v < v_r; P_rated for v_r ≤ v < v_co; 0 otherwise. AEP = 8760 · ∫ P(v) · f(v) dv, integrated numerically in 0.5 m/s bins. Caveat: No wake losses, availability losses, or electrical losses applied. For bankable estimates use measured site data, a Weibull fit, and wake models.
