Wind Energy Conservation with Grid Levelling for Transient Loads

摘要

The paper discusses the maximum power point tracking in a grid connected PMSG based WECS. To the variablespeed wind turbine, if the rotor speed can always be adjusted to make the turbine operate under optimum tip speed ratio then it means that the turbine realizes the MPPT operation. For this purpose the P and O tracking algorithm is adopted. In addition to fully recognize the wind energy it is necessary to integrate it to the grid and hence grid parameters are regulated as well. The proposed system is developed in Matlab environment.
