An Improved Scheme of Power Quality in Wind Generation System Using Novel Nonlinear PI Controller

Abstract

This paper is based on the research of low wind speed area, which is velocity alters rapidly and the wind power concentration is lower. Not only the maximum power point tracking (MPPT) strategy for Wind Generation System would be even more demanding, but also the efficiency of converter in generator sider and gird side by voltage space vector PWM (SVPWM) in field oriented control would be even more achieving. The reaction of controller is the key of control scheme. The wind power system in low wind speed area needs more smoothing and short time oscillation. A new type of nonlinear PI controller has devoted to the enhancement of wind generation system adoption in low wind speed area. The result has presented the comparison between tradition controller and novel controller via Matlab/Simulink.
