Improvement of the performances MPPT system of wind generation

Abstract

The wind turbines used for power generation should enable to produce maximum power, making best use of available energy in the wind. A specific known terminology: Maximum Power Point Tracking (MPPT) must be introduced to obtain maximum energy efficiency. The strategy from this command is to control the electromagnetic torque to adjust the speed mechanics to maximize the electrical power generated. There are two families from control structures, the strategy from maximizing the power with and without velocity control. The aim of this paper is to evaluate the performances of two types of MPPT controllers mentioned on an 7.5 kW test bench containing a DFIG and we interested to compare this two strategies from maximizing the power extracted for a wind generation system with a horizontal axis The corresponding simulation model are described in section III. The studied MPPT controllers are presented results are given, analyzed and discussed in part in part IV. Finally, In last part, extracts some conclusions on this paper.
