As renewable energy resources such as wind become more prolific, the challenges in utilizing these resources to their full efficiency come to the forefront of power system engineers. Although the sustainability of such alternative energy resources is attractive, the ability to obtain satisfactory efficiency has been difficult until recent advances in nonlinear control technologies. The subject of...
Permanent magnet synchronous generators (PMSGs) are commonly used as a variable speed generator in wind energy systems. This paper describes a maximum power point tracking (MPPT) scheme for a PMSG-based wind energy conversion system (WECS) in which a buck-boost converter is used to handle a wide range of wind speeds. A closed-loop with a PWM inverter forces the WECS to extract the maximum power available...
This paper develops a framework of maximum power point tracking (MPPT) of doubly-fed induction generator (DFIG) based and permanent magnet synchronous generator (PMSG) based wind energy systems. The principles of MPPT in various wind generators are firstly investigated and feedback control schemes to realize MPPT with/without wind speed measurements are presented. Stability analysis of the wind energy...
