Relative Study of MPPT Algorithms using Wind Turbines with Different Dimensions
Wind energy is considered as a most reliable and developed renewable energy source. With the rapid growth in this area, new techniques and control are seen to achieve maximum utilization of wind power and operating the wind turbine (WT) at its optimal condition. Various maximum power point tracking (MPPT) algorithms are available; however, a choice has to be made for the appropriate one as each algorithm has its own merits and demerits. This paper presents the comparison of three MPPT control algorithms: Tip speed ratio (TSR), Hili c1imb search (HCS) and Fuzzy based MPPT algorithm on three different size turbines of different power rating, in terms of their ability to extract maximum power output, number of iterations required i.e. speed responses and complexity using MATLAB. The results obtained in this paper may help the researchers to refer a suitable algorithm for their requirement.
