New MPPT control for wind conversion system based PMSG and a comparaison to conventionals approachs

This study aims to apply the ripple correlation current (RCC) approach, which is an MPPT search algorithm used in photovoltaic systems. To extract the maximum power, a wind conversion structure based on a permanent magnet synchronous generator (PMSG), a three-phase rectifier and a boost converter is used. The choice of this structure is justified by the reliability, simplicity of implementation and control. This paper discusses the performance evaluation of a MPPT algorithms called RCC (ripple correlation current) in comparison with the conventional methods. To achieve this objective, four criteria are chosen: speed convergence, need of mechanical sensors, accuracy and dependence of the previous position. The main features presented in this paper are as follows: (a) modeling the power wind conversion systems, (b) presenting and detailing each MPPT algorithm (c) showing the proposed RCC MPPT and it implementation results, (d) conducting a discussion and give an evaluation performance of the proposed approach according to the criteria cited in comparison with the conventional methods.
