In order to maximize the power utilization from the variable speed wind energy conversion system (WECS), maximum power point tracking (MPPT) controller is necessary. The system considered consists of wind turbine coupled to a permanent magnet synchronous generator (PMSG) and the output of the PMSG is given to a bridge rectifier, which is fed to the DC-DC boost converter where the duty ratio of the converter is controlled to vary the input voltage and current to track the maximum power point using the Hill Climb Search (HCS) technique. The simulation and hardware test result of the maximum power point tracker are presented and discussed. This work presents a simplified test setup to enable the testing of wind turbine maximum power point tracking by setting up an open loop wind turbine and PMSG emulator using the DC motor alternator setup without any complicated controllers.
