Abstract:
The purpose of this paper is to present an optimal control structure for a wind turbine with DFIG based onmethod Linear Quadratic Regulator with Integral-Action (LQI), and to see the behavior of this topology when to the system is applied a random variation in the wind, simulating the real behavior of the wind. In addition, an analysis of injection current and voltage harmonics on the grid, when applied a nonlinear load on the connection point to the grid bus, for checking whether the levels of harmonics in the grid are released within the recommendations in the IEEE 519.
