Dynamic model for energy predicting in WECS

Abstract

This paper presents a dynamic simulation model of a wind generator, that allow to predict the quantity of removable energy in a specific place, using as initial condition wind measurements register in that place. The model is composed of four modules.The frist one is used to model de wind behaviour. The second is orientend to the aerodynamics model. The third is focused on the mechanical connection between the hub and the electrical machine. Finally, the fourth is dedicated to the electrical machine. The first model dedicated to the wind behaviour, includes an stochastic model. The aerodynamics conversion is base on the Strip Theory. The connection between the hub and the electrical machine used the mechanical differential equations. Finally, the electrical machine is modelled using the Power System Blockset including in Matlab Simulink.
