“…These results are comparable to the ones recently published in [21]. These results were achieved even when working with much higher DFIG model parameters such as the mutual inductance which was 11.58 times higher than the one in [21], 26.85 times higher leakage inductances, and more than 80 times higher resistances. MBPC can be scaled from a low-power to a higher-power setup one with relative simplicity.…”

“…Present trends of investigation in variable-speed wind turbine systems include new power control techniques and new technology in power converters to achieve better efficiency [13], [32], power quality and maximum wind power capture [33], reliability [34], [35], ride-through capability [36], [37], and longer life cycle cost of the system including power electronics [38]- [40]. Predictive control has been implemented in IMCs for motor drives (which are mainly aimed to military and aerospace applications where size and weight are relevant issues [3], [4]) as well as in DFIGs for renewable energy systems [21]. Other recent studies focus their efforts on achieving better efficiency solutions with IMC-DFIG systems as in [41]- [43], and for the specific topic of low voltage ride-through in [44]; the four of them featuring different techniques such as fuzzy logic, sigma-delta modulation and space vector modulation.…”

A novel predictive rotor current control scheme for a doubly fed induction generator (DFIG) is implemented to perform the DFIG grid synchronization with a fast dynamic response. With this control strategy applied to an experimental setup, the rotor currents swiftly follow the necessary reference for grid synchronization in the range of ±30% of the generator rated shaft speed. The DFIG and converter discrete models are used to predict the behavior of the rotor currents. By minimizing the error between the references and the predictive rotor currents for each of the valid states of the converter, the best-suited switching state is selected and applied at the next sampling time. In order to validate the feasibility of implementing this approach, simulations and experiments were carried out for various shaft speed profiles.

This paper presents a Predictive Direct Power Control Applied to the Doubly Fed Induction Generator operating with or without voltage dip, in variable speed operation. The predictive controller is obtained from state-space DFIG model. The control law is derived by optimization of a cost function that considers the difference between the predicted outputs -stator active and reactive powers -and their references. It used a discrete state-space model to describe the system. As the voltage dip is not predicted, it is considered to be a disturbance in the control algorithm. Digital simulations are performed to verify the efficiency potential of the proposed controller.

A new design of a digital control system for the grid-connected doubly fed induction generator is described in this paper. A discrete-time state-space model of the controlled system is obtained in the stator stationary reference frame. Using this model, a discrete-time sliding mode based control system is designed. Its tasks are the grid synchronization and the direct power control. The discrete-time equivalent control method is applied, and the control vector is calculated from the samples of voltages and currents. The control vector is converted to a switching sequence in a power converter using the space vector modulation. The modulation period is equal to the sampling period. A disturbance compensator is designed to eliminate the influence of the discretization effect and model uncertainties. In this way, a robust control system with a constant switching frequency is designed. Its digital hardware implementation is simple. The performance of the designed control system is tested on a simulation model.978-1-4799-7800-7/15/$31.00 ©2015 IEEE
