“…The methodology described in this work could be used by electrical machine manufacturers to optimise the efficiency of SWTs [12] or to reduce the generator size because a new electrical machine with a capacitor bank would include the following modifications in order to obtain the same power: less copper (the capacitor bank decreases the current that flows through the electrical machine), smaller magnet size (magnetising effect of the capacitors) and fewer magnetic plates.…”

The increasing use of small-wind energy has made it necessary to develop new methods that improve the efficiency of this technology. This is best done by considering the interaction between the various components, such as wind rotors, electrical generators, rectifiers and inverters, as opposed to studying the individual components in isolation.Hence, this chapter describes a methodology to increase the efficiency of small-wind turbines (SWTs) equipped with an electrical machine, rectifier and inverter. To achieve this objective, capacitor banks will be connected between the electrical machine and the rectifier. This methodology is motivated by two clear aims. The first one is to operate the SWT with its maximum power coefficient (C p ). The second one is to select the most suitable capacitor bank for each wind speed in order to optimise the energy supplied to the grid.

“…Nevertheless, SSWTs are becoming increasingly competitive with cost issues as aerodynamic, electronics design, pitch control, energy storage and integration units are under great improvements [18,20,26,91]. Basic control methods for SSWTs use a fixed voltage reference for the generator to vary the torque when varying the current through changes in voltage differential.…”

“…Horizontal Axis Wind Turbines (HAWTs) have been demonstrated to be the transcendent machine tools in extracting the energy from the wind (Hau, 2006;Gipe, 2004); these machines possess a number of advantages when compared with Vertical Axis Wind Turbines (VAWTs), such as higher energy efficiency, more mechanical stability, less sensitiveness to off design conditions, etc. Thus, effective extraction of the wind stream energy with less energy waste, obtaining a comprehensive understanding of the energy conversion phenomena, and economic analysis of these systems have become an area of concern for technology leaders as well as an area of interest for researchers (Mehta et al, 2014;Arroyo et al, 2013;Castellani and Vignaroli, 2013;Castellani and Garinei, 2013;McKenna et al, 2014;Jung and Kwon, 2013;Jha, 2010;Burton et al, 2011;Wood, 2011). In this regard, optimization of geometrical properties of wind turbine blades has been investigated using various approaches.…”
