Wind turbine power tracking using an improved multimodel quadratic approach

摘要: In this paper, an improved multimodel optimal quadratic control structure for variable speed, pitch regulated wind turbines (operating at high speeds) is proposed in order to integrate levels of power actively provide a primary reserve frequency control. On the basis nonlinear model studied plant, and taking into account speed fluctuations, electrical variation, linear description derived turbine, used synthesis law involving state feedback, integral action output reference model. This new allows rapid transition turbine generated between different desired set values. tracking ensured with high-performance behavior all other variables: generator rotational speeds mechanical shaft torque; smooth adequate evolution variables.
