“…The optimal rotor reactive current value was derived for minimal copper losses in [4][5][6][7][8]. These methods only consider copper loss minimization, but the reactive power from the stator is not zero, so the required power factor at the generator terminals is regulated by the grid-side converter, which will cause loss on the converter.…”

Abstract-The paper deals with control techniques for minimizing the operating loss of doubly fed induction generator based wind generation systems when providing reactive power. The proposed method achieves its goal through controlling the rotor side q-axis current in the synchronous reference frame. The formula for the control reference is explicitly deduced in this paper considering the losses of the generator, the power electronic devices and the filter. Three control strategies are compared with the proposed method under different wind speeds and different reactive power references. The simulation results validate the effectiveness of the proposed method.

Since the Doubly Fed Induction Generator (DFIG) converters are designed by the slip power (a fraction 25-30% of the total power) to achieve full control of the generator, there is not enough capacity to provide reactive power when the voltage dips below the tolerable grid voltage level at the Point of Common Coupling (PCC). We propose in this paper to use the Static Synchronous Compensator (STATCOM) for compensating the grid voltage dip to improve the power quality in a weak grid or asymmetrical load. The simplified active and reactive power control strategies of a 6 MIVA wind farm with DFIG are described. The Maximal Power Point Tracking (MPPT) algorithm is implemented. The simulation results using the platform between Matlab/Simulink and PLECS demonstrate the good performance of the wind farm with DFIG and STATCOM, validating the analytical conclusions.

“…In order to capture maximum wind energy as soon as possible, the rotational speed control of the generator connected to wind turbine is one of the most significant features characterizing the overall design of a wind power plant. Both domestic and foreign scholars propose many control strategies, such as optimal control [2], sliding mode control [3], adaptive control [4], fuzzy control [5], and so on. However, these methods have the complicated theory basic, require a large amount of calculation and take much time to solve.…”

Based on the analysis of the wind turbine operation characteristics, the essence of the maximum wind energy tracking problem is transformed into the speed control problem of the generator. For the variable speed constant frequency brushless doubly-fed wind power generation system suffering from the wind energy uncertainties and instability, the model is established, and the disturbance signals are bounded by L 2 norm. L 2 robust control method is adopted to design a controller, which has the invariable structure and parameters to guarantee the system to meet performance requirements under the worst uncertainties. The proposed robust controller enables the generation system to be better in robustness against parameters uncertainties, to rapidly track the wind speed, and further to achieve the maximum wind energy tracking, which is helpful to enhance the wind energy efficiency.Index Terms -brushless doubly-fed generator; L 2 norm; robust control; wind power generation; maximum wind energy tracking.
