MAXIMUM POWER POINT TRACKING ALGORITHMS FOR WIND ENERGY SYSTEM: A REVIEW

Abstract

This paper reviews and studies the state of the art available
maximum power point tracking (MPPT) algorithms. Due
to the nature of wind which is instantaneously changing,
there is only one optimal generator speed desirable at any
one time that ensures maximum energy is harvested from
the available wind. Therefore, including a controller that is
able to track the maximum peak regardless of any wind
speed is essential. The available maximum power point
tracking (MPPT) algorithms can be classified according to
the control variable, namely with and without sensor, and
also the technique used to locate the maximum peak. A
comparison has been made on the performance of the
selected MPPT algorithms based on various speed
responses and the ability to achieve the maximum energy
yield. The tracking performance is performed by
simulating wind energy system using the
MATLAB/Simulink simulation package. Besides that, a
brief and critical discussion is made on the differences of
available MPPT algorithms for wind energy system,
followed by a conclusion.
