Abstract

Over the last decade, wind turbine technology has made remarkable progress and new turbines with great variety has been proposed every year. Each of these products has its own advantages and can be very practical when operated under suitable conditions. However, due to their extensive functionalities and wide variety, selecting and operating the appropriate turbine often becomes a challenging and highly specialized task. The primary objective of this research is to examine and compare the advantages and disadvantages of wind energy harvesters, with the main focus on miniature wind turbines. The study contributes to the development of existing technical knowledge in the field of wind energy harvesters by compiling previous research on small wind turbines based on various physical characteristics such as power, structure, and performance. In addition, the article evaluates different harvesters based on statistical information and assesses innovative technologies and the combination of different energy harvesting methods. The comprehensive classification provided for these miniature systems reveals that, besides conventional wind turbines like vertical and horizontal axis turbines, new harvesters such as vortex-bladeless, EWICON, Sophonian, and Involex can perform well under suitable conditions, considering their working principles, energy conversion mechanism, and physical structure.
