the major problem of wind turbines is the great variability of wind power production. the dynamic change of the wind speed returns the quantity of the power injected to networks. therefore, wind–thermal generation scheduling problem plays a key role to implement clean power producers in a competitive environment. in deregulated power systems, the scheduling problem has various objectives than i...

Abstract. Stochastic dynamic analysis of linear or nonlinear multi-degree-of-freedom systems excited by multi-variated processes is usually conducted using digital Monte Carlo (MC) simulation. Since in structural few modal shapes contribute to the response nodal space, computational burden MC simulation mainly related input process. Usually, generation samples Gaussian process performed with ai...
