Online multi-step prediction for wind speeds and solar irradiation: Evaluation of prediction errors

Hirata, Yoshito; Yamada, Taiji; Takahashi, Jun; Aihara, … - In: Renewable Energy 67 (2014) C, pp. 35-39

We propose a general method for predicting multiple steps ahead of our target system and estimating simultaneously the prediction errors in a real time. The requirement of the proposed method is that we have a time series of the target system. We demonstrate the method by artificial data, real...

Numerical methods for investigation of destructive wind energy dissipation by bridges

Domaingo, Andreas; Janjic, Dorian - In: International Journal of Global Energy Issues 32 (2009) 3, pp. 212-226

Many bridges are located at especially unfavourable places considering the local wind power and turbulence. Therefore it turns out that finding an optimal balance between structural safety and erection costs depends strongly on a proper wind modelling and investigation. Several aspects must be...
