Wind Energy Conversion Systems are the most striking renewable energy resources available to generate the electricity. Doubly-fed Induction Generator (DFIG) based wind turbine with variable speed is the most common wind turbine in the growing wind market. In any WECS, power flow must be maintained at all instant irrespective of any fault in the system. This paper deals with fault tolerant contr...

A control strategy is realized which solve the problem of output power regulation of variable speed wind energy conversion systems by combining a linear control for blade pitch angle with a nonlinear H∞ torque control which mitigate the effects of external disturbances that occur at the input and output of the system. The controller exhibits better power and speed regulation when compared to cl...

In this paper the maximum power point tracking (MPPT) algorithms for wind energy systems arereviewed. As the amounts of power produced in wind power plants is changing due to theinstantaneous changing nature of the wind, it is desirable to determine the one optimal generatorspeed that ensures maximum energy yield. Thus, it is important to include a controller that cantrack the maximum peak rega...

Energy harvesting has become an increasingly important topic thanks to the advantages in renewability and environmental friendliness. In this paper, a comprehensive study on contemporary portable wind energy harvesters has been conducted. The electrical power generation methods of portable wind energy harvesters are surveyed in three major groups, piezoelectric-, electromagnetic-, and electrost...

This paper aims to increase the power production of gearless permanent magnet synchronous generator (PMSG) based wind energy conversion systems (WECS) in strong (greater than 25 m/s) speed regions. In general, most turbines cut off when is over cut-out rate; as a result, generation farm decreases. study introduces look-up table pitch angle and rotational control generate extra region. Consequen...

With the increasing penetration of wind energy into power system, wind energy conversion systems (WECSs) should be able to control the power flow for limited as well as maximum power point tracking. In contrast to the traditional pitch angle control, this paper focusses on field oriented speed control of permanent magnet synchronous generator (PMSG) for controlling the active power flow based o...
