This paper presents a voltage control methodology that provides a doubly-fed induction generator (DFIG)-based wind farm with the capability to provide voltage regulation. The controller manipulates dynamically the reactive power from the voltage source converter (VSC) to control the voltage at a specified location. Since a proportional-plus-integral (PI) controller is popularly used in power systems,...
The paper presents the dynamic model and control schemes of a variable speed pitch wind turbine with permanent magnet synchronous generator (PMSG). The model includes a PMSG model, a pitch-angled controlled wind turbine model and a drive train model. The drive train model uses one-mass model to represent the mechanical characteristics of the generator set. The generator model is established in the...
The modeling and control design for a grid- connected wind-energy converter system including a matrix converter are presented. A nonlinear model is developed including equations of mechanical aerodynamic conversion, drive train, matrix converter, and squirrel-cage induction generator. The model is linearized, and the steady-state and transient responses of the small-signal model are evaluated and...
