The frequency regulation rate and operation stability of a doubly fed induction generator (DFIG) based on virtual synchronous (VSG) strategy decreases under large-power-angle conditions, which reduces the grid support capacity. This paper proposes compound adaptive parameter (CAP) coordinated primary (CPFR) strategies to improve capacity in terms multiple dimensions transient properties, condit...

In order to control the output power of wind application (WA) based on doubly fed induction generator (DFIG). The simple (SC) strategy approaches via flux orientation and neglecting resistance (FOANR) decoupled axes is most common used in many previous studies, However this FOANR present a linear synthesis, mainly DFIG model sensitive internal external disturbances, This research paper contribu...

This paper discusses a control system for the converter of doubly fed induction generator (DFIG) driven by wind energy. The DFIG consists two main parts; rotor side (RSC) and grid (GSC). Two advanced methods GSC are presented here in this paper; vector strategy based on pulse width modulation (PWM) direct power (DPC). DPC is switching table voltage selection. In addition to position, quadrature...

According to the coordination control of a dynamic voltage restorer (DVR) and an inductive fault current limiter (FCL), this paper proposes efficient low-voltage ride-through (LVRT) scheme for doubly fed induction generator (DFIG) based wind turbine. The DVR is located DFIG’s stator circuit stabilizing terminal decreasing current. FCL connected rotor suppressing overcurrent protecting converter...

This paper modeled a doubly fed induction generator (DFIG) based offshore wind farm integrated through a voltage source converter –based high voltage direct current (VSC-HVDC) transmission system, which is collected with infinite bus for small signal stability analysis. The control system of HVDC system is considered for the stability analysis. The impact of the VSC control parameters on the ne...

-In this paper we present a new control structure to extract the maximum power of a wind energy conversion system based on the double fed induction generator (DFIG). The proposed algorithm combines the nonlinear Backstepping approach and the field orientation scheme applied to control the rotor side converter (RSC) and the grid side converter (GSC) of the DFIG. The proposed strategy is asymptot...

A fault current limiter (FCL) may be applied to assist the low-voltage ride-through (LVRT) of a doubly fed induction generator (DFIG). FCLs with fixed impedance, lack flexibility adjust their impedance adapt different LVRT scenarios. The direct switch-in and -out fixed-impedance FCL yields transient electromagnetic oscillations in DFIG, which need addressed. In this paper, variable-impedance is...

This paper offers novel non-linear control of a doubly fed induction generator (DFIG) and unified power flow controller (UPFC) for transient stability increment with energy function (TEF) sliding mode observer in system. First, the TEF technique is considered damping system synchronous (SG), DFIG, UPFC, then time-derivative signals are estimated by second-order observer. The importance issue em...

For doubly-fed induction generator (DFIG)-based wind turbines (WTs), various advanced control schemes have been proposed to achieve the low voltage ride through (LVRT) capability, whose parameters design is significantly reliant on rotor electromotive force (EMF) of DFIG-based WTs. However, influence current EMF usually ignored in existing studies, which cannot fully reflect transient character...
