Different Technique of Maximum Power Point Tracking (MPPT) For Wind Power Generation

Abstract

this paper is nominate a new different method an improved maximum power point tracking (MPPT) method
for wind power system. A different control method for MPPT of wind turbine adjusting load characteristic was
nominated in this paper. In different methods of M PPT; By using algorithm employed in wind energy conversion
system(WECS) the major effect concerning Hill Climb Search (HCS) is it’s inefficiency in detecting peak power when
there change wind speed. The HCS generate oscillations in delivered power once of this peak value detected. A modified
HCS algorithm is nominated in this paper to overcome these limitations. In this algorithm used a variable duty cycle to
reduce the oscillation in delivered power once the maximum power point (MPP) is detected ; The wind power
management system based on DC to DC convertor was designed .The MPPT pull maximum power from the wind turbine
from cut in to variable wind velocity by sensing only DC link power .The maximum power point (MPP) step and search
algorithm in addition to the DC to DC are simulated generate by using METLAB software and result generate show
that the DC to DC converter topology can generated the maximum power tracking control of the wind turbine ; MPPT
method with hysteresis control, the hysteresis controller is similar to that used in the typical P&O (production &
observation) control. This method is control the output of wind turbine is unable to reach maximum power, in hysteresis
controller different duty ratio within the hysteresis band to correct for operating point by using control method; MPPT
by using fuzzy logic controller (FLC), in this method for MPPT a fuzzy logic control is nominated for maximum power
tracking in wind turbine control to permanent magnet synchronous generator (PMSG). By using FLC tracks the MPP by
measurement the load voltage and current, this controller calculates the load power and transfer through the fuzzy logic
system. In this paper by using this method main aim is design of the FLC controller in the mode of boost converter (DCDC converter). FLC method is allows the MPPT controller output (duty cycle) adjust the voltage input to the converter to
take MPP of wind power generating system.
