Modelado, simulación y control MPPT de un convertidor Cûk en aplicaciones de microgeneración eólica.

Abstract

In order to minimize carbon dioxide emissions, alternative energy generation has increased its participation around the world, especially in first-world countries. This is the case of eolic energy, whose installed power has grown in recent years. However, the biggest problem with these kinds of generation systems is that the primary energy fluctuates over time. In order to fix this, algorithms for control maximum power extraction (MPPT) are required to be implemented. Because of that, the present project focuses on the design, modeling, and simulation of a wind energy conversion system (WECS), which electric drive consists of a Cûk DC/DC converter. It is analyzed using the small signal method to get the best theoretical approximation of the real behavior of the converter. Along with this, associated controllers are developed to get an appropriate response from the system to set point changes and perturbations. These controllers work together with the maximum point power tracking algorithm (MPPT) by Perturb & Observe type.
