Maximum Power Point Tracking from a Wind Turbine Emulator Using a DC-DC Converter Controlled

Abstract

Development and utilization of wind energy has become an important part of world sustainable energy development strategy. A control method realizing maximum power point tracking of wind turbine through adjusting the load characteristics was proposed in this article. The power management system based on DC/DC convertors was designed. The maximum power point tracker (MPPT) extracts maximum power from the wind turbine from cut-in to rated wind velocity by sensing only dc link power. The MPPT step and search algorithm in addition to the DC/DC are simulated using MATLAB-SIMULINK software. The results show that the DC/DC convertors topology can realize the maximum power point tracking control of the wind turbine. © 2014 SERSC.
