Type-C wind turbine model order reduction and parameter identification
Due to the increasing penetration of wind power, engineers are finding it useful to have models to investigate wind turbine performance. For different applications, an accurate modeling of aerodynamics, power electronics, electrical transients, or control systems are necessary. In other scenarios, …

An appraisal of wind energy conversion systems for agricultural enterprises.
A detailed wind prediction model is developed, which predicts wind regimes and energy outputs from wind turbine generators at locations that are remote from sites where long-term wind data is available. The model accounts for the local, directional influences on the wind flow of topography and …
