ABSTRACT
This paper presents a study on maximum power point tracking for a wind turbine generation (WTG). The general structure of a WTG will be introduced, including mechanical and electrical conversion blocks, to make clear about the role of all units. Moreover, mathematical models of both turbine and generator type permanent magnet synchronous generator (PMSG) will be presented to simulate and evaluate the operation of WTG. Working regions of the wind turbine corresponding to different values of wind speed and contents of some techniques to determine maximum power point will be made detailed. Hill climb search (HCS) is chosen to simulate and analyzed deeply to evaluate the ability to apply to real applications. Simulation results are carried out by MATLAB/Simulink software. By using a variation scenario of wind speed, the role of power converter and HCS controller will be presented in some simulation results about power and current at output terminals of the generator to show the ability to track instantaneous maximum power point. Research results show the high effectiveness and availability of HCS technique in real wind power system.
Keywords: Maximum power point, Maximum power point tracking, Wind turbine, Wind generator, Wind speed, PMSG.
