An Adapted Method for a Small Wind Turbine to Extract the Optimal Power
Authors: , , ,
Abstract: In this paper, the control of the wind energy conversion systems (WECS) is synthesized. The considered WECS includes a two-bladed wind turbine and a permanent magnet synchronous generator (PMSG). First, a model of the whole controlled system is developed in the Park-coordinates and given a state space representation. A multi-loop controller is designed to meet the main control objective, i.e., speed reference optimization in order to extract maximum wind energy whatever the wind speed. For this, a speed-reference optimizer is developed. This approach uses an identification method to determine a mathematical function generating the optimal speed reference (Maximum Power Point Tracking). The speed-reference optimizer and the control law performances are illustrated through numerical simulations. All control objectives are proved to be asymptotically achieved.
