Improved MPPT controllers for wind generation system based on hill climbing technique

This paper introduces a Maximum Power Point Tracking (MPPT) controllers for Wind Generation System (WGS) based on a small-scale low cost application. The MPPT algorithm has been developed based on Hill climbing technique. Two controllers have been designed using Proportional and Integral (PI) control and Sliding Mode Control (SMC) scheme. Using back-EMF observer, the rotational speed has been estimated in of the controller while the speed is measured in the other one. Both the controllers are independent of a wind speed measurement. This paper develops a dynamic model of the WGS in the dq reference frame. MATLAB/SIMULINK has been used to analyze the behavior of developed controllers. As a final point, an evaluation of the suggested controller with the classical controller in terms of dynamic performance.
