system of pv control for basic with error

A hardware-in-the-loop simulation of a wind energy conversion system is used to assess a MPPT strategy for different velocities. The actual system is composed of the blade, a mechanical power train, a squirrel cage induction generator and power electronics. The experimental set-up consists of a DC drive connected to the induction generator. The DC machine is controlled to impose the same behavior as the wind turbine to the induction generator. Fluctuations of wind velocity and non-linear characteristics of the turbine are taken into account. All numerous model and controls blocks are organized according to Energetic Macroscopic Representation for real-time implementation. A very simple MPPT strategy without wind velocity measurement is achieved using a look-up table. This strategy includes a rotation speed limitation. Experimental results are provided for weak and medium wind profiles.
