Abstract
This paper investigates the use of the linear quadratic Gaussian controller to control the voltage and frequency of a wind energy conversion scheme. This scheme cosists of a wind turbine and induction generator connected to the utility grid via AC-DC-AC asynchronous link. The control objective aims to regulate the rectifier output voltage and track the maximum available wind power. This is accomplished via controlling the firing angles of the rectifier and the inverter. The complete nonlinear dynamic model of the system has been described and linearized arround an operating point. The standard Kalman filter technique has been employed to estimate the full states of the system. The computational burden has been minimized to a great extent by computing the optimal state feedback gains and the Kalman state space model off-line. The proposed controller has the advantages of robustness, fast response and good performance. The wind energy scheme with the proposed controller has been tested through a step change in wind speed. Simulation results show that accurate tracking performance of the proposed wind energy scheme has been achieved. Moreover, this scheme is robust against the parameters variation and eliminates the influence of modeling and measurement noises.
