A Review on Various MPPT Techniques for Wind Energy Conversion System

TLDR: P perturb and observe, Incremental Conductance and Fuzzy logic control algorithms along with mechanical MPPT algorithms track the maximum power for varying wind conditions, which maximizes power output.

Abstract: Different types of renewable resources are need of the hour as fossil fuels are on The verge of extinction but electricity demand is increasing exponentially. In reality renewable energy is available in such a huge amount that it can provide 3078 times the present global energy need. Wind energy is one of these sources and having potential to generate 200 times energy than require globally. It is the oldest source of energy on the earth and from 1887 only it started to use for electricity generation. The efficiency of wind turbine, gear and generator decides the overall efficiency among this wind turbine is having scope of improvement. The wind turbine will generate maximum power if wind variation is less but it is not in someone's hand. Thus an MPPT technique comes into picture and maximizes power output. Various MPPT techniques are present till date, but in this paper we proposed perturb and observe, Incremental Conductance and Fuzzy logic control algorithms along with mechanical MPPT i.e. pitch control. These MPPT algorithms track the maximum power for varying wind conditions. Pitch control comes handy when speed increases more than rated speed, it will change pitch angle in such a way that it will rotate and constant speed to generate maximum power.
