Abstract

Accurate modeling of wind velocity distribution is essential for optimizing wind energy generation and improving resource assessments. This study presents a predictive stochastic model utilizing the Weibull distribution, with its parameters optimized using the Particle Swarm Optimization (PSO) algorithm—a robust metaheuristic technique. Wind speed data collected over a one-year period in the Aba region were analyzed. The PSO-based estimation significantly outperformed traditional methods like Maximum Likelihood Estimation (MLE), yielding lower error margins and higher correlation with empirical data. The optimized model achieved a high coefficient of determination (R² = 0.972) and a reduced Root Mean Square Error (RMSE = 0.0087), confirming its effectiveness. The study demonstrates the potential of PSO-enhanced models in supporting reliable wind energy resource evaluation and system design.
