“…Hence, in [30] a SMC method was proposed to control the GSC and (RSCs of a DFIG-based WECS, where an unbalanced and harmonically distorted grid voltage condition is considered. In [31], the concept of extended active power is proposed to simplify the controller design process when the grid voltages are unbalanced. In [32], a sliding mode approach incorporating the feedback linearization theory is proposed to maintain the converter currents when the grid voltage level is far below the nominal values.…”

“…The introduction of super-twisting algorithms helps to avoid the utilization of discontinuous components in the control input, thus the chattering phenomena can be resolved if the system parameters are known [41]. In [31], a second order SMC scheme is proposed for power optimization of DFIG-based WECS. However, the major drawback of HOSMC is its dependence on the parametric uncertainty bounds which are usually difficult to estimate in practical scenarios [41,42], making it impractical in DFIG wind turbine control.…”

This paper proposes a novel sliding mode control (SMC) technique for doubly fed induction generators (DFIGs) based on the fast exponential reaching law (FERL). The proposed FERL-based SMC is capable of reducing to a large extent the chattering phenomena existing in the sliding stage. Meanwhile, the reaching stage is accelerated with the introduction of an adaptive gain. The proposed method is employed in a DFIG-based wind energy conversion system (WECS) for direct power control (DPC). The FERL-based DPC approach is tested with simulations conducted in Matlab/Simulink under the scenarios of unbalanced grid voltage, grid fault conditions and highly unstable wind speed accompanied by an experimental study. The simulations and experimental results reveal the better performance of the proposed control method in active/reactive power tracking and dc-link voltage maintenance.

An adaptive integral sliding mode direct power control (AISMC DPC) strategy for voltage source converter medium voltage direct current (VSC-MVDC) system converter stations (CS) is proposed in this paper. For high power VSC-based applications, the time delays in the control loops have significant adverse impacts on system performance and robustness. Aiming at these problems, an integral sliding mode control (ISMC) based DPC controller, consisting of the proportional and the integral control laws, is firstly designed for the CS to realize accurate power regulation objective. Then, based on the ISMC DPC controller, an ac line parameter adaptive scheme with error compensation, i.e., the AISMC DPC strategy is proposed, to improve the robustness and the transient performance of the system. Simulation studies on a 2-terminal VSC-MVDC system are conducted to verify the effectiveness of the proposed AISMC DPC strategy. The results show that the strategy provides satisfactory performance of the system over wide range of operating conditions.

SummaryIn this study, an improved anti‐windup proportional‐integral predictive direct power control strategy with a phase‐locked loop (PLL) is proposed and applied to a three‐level shunt active power filter (SAPF) neutral point clamped (NPC) inverter using space vector modulation (SVM) technique. The SAPF has to ensure sinusoidal waveforms and unity power factor in the grid side, by eliminating harmonic currents and compensating reactive power of the nonlinear loads. Active and reactive powers as well as the DC bus voltage controls are performed using anti‐windup proportional and integral actions with a predictive algorithm, without a need for an exhaustive mathematical model. The control law is modulated using the SVM technique allowing fixed switching frequency and low power ripples. The performances of the suggested control have been verified through an electronic STM32F407 card under diverse and severe conditions. The obtained results confirmed the expected objectives in terms of current and voltage quality, robustness, and dynamic response.
