Abstract
When the wind power electricity system working above the rated wind speed, the disturbed wind speed can lead to the output ripple easily, which causes a significant negative influence on the stability of the power grid. In order to overcome this disadvantage, this paper discusses the mixed \(H_2/H_{\infty }\) pitch angle control design problem for the nonlinear wind turbine generator system, where the turbulence is regarded as the disturbance input. Especially, the global exact linearization and the pole placement techniques are also applied to guarantee the desired control performance and expected dynamic characteristics in the situation of a large-scale variety of the system operation points. The simulation results show the effectiveness of the proposed method.
