Evaluation of Power Extraction to Linear Gain Scheduling Controllers in a Small Wind Energy Conversion System
Renewable energy sources have focused a special attention in wind energy conversion systems, where the goal is maximal power extraction. This paper presents an evaluation of the linear controllers eigen structure assingment, linear quadratic regulator, and the robust loop shaping design procedure actuating on a small wind energy conversion system with a permanent magnet synchronous generator, the rectification is made by a diodes bridge, and the direct current is controlled by a DC-DC converter. The analysis is made calculating the mean square error of the optimal tip speed ratio and the tip speed ratio developed by each regulator, the numerical results also show the performance of the power coefficient, power extracted from a wind profile, and the operation around the optimal regime characteristic. The proposed system works under variable wind speed, and validate the methodology applied.
