The power generation with non-renewable energy sources has very harmful effects on the environment as well as these sources are depleting. On the other side the renewable energy sources are quite unpredictable source of power. The best trade-off is to use the combination of both kind of sources to make a hybrid system so that their individual power generation constraints can be overcome. The hy...

This article presents a sliding mode control (SMC) with artificial neural network (ANN) regulator for the doubly fed induction generator (DFIG) using two-level neural pulse width modulation (NPWM) technique. The proposed control scheme of the DFIG-based wind turbine system (WTS) combines the advantages of SMC control and ANN regulator. The reaching conditions, robustness and stability of the sy...

In this study, robust and high-performance vector control of a rotor side converter (RSC) is performed for the stability efficient operation doubly fed induction generator (DFIG) based on variable speed wind turbine (VSWT). The mathematical model DFIG simulated by using Matlab/Simulink. amplitude frequency voltage in controlled different values load speeds. experimental DFIG-based system set up...

The Brushless Doubly-Fed Reluctance Generator (BDFRG) is a potential alternative to the Doubly Fed Induction (DFIG) in wind power applications owing its reasonable cost, competitive performance, and high reliability. In comparison with (BDFIG), BDFRG more efficient easier control cage-less rotor. One of most preferable advantages over DFIG inherently better performance under unbalanced grid con...

Abstract To suppress the subsynchronous oscillation in doubly-fed induction generator (DFIG) system with Static VAR Generator (SVG), a feedback linearization control (FLC) method for rotor-side converter (RSC) is proposed, and its effect under small disturbances analyzed verified. Firstly, 22-order time-domain model of DFIG SVG established. Secondly, combined principle linearization, correspond...

With the increasing utilization of electronic equipment in power system, sub-synchronous oscillation (SSO) has occurred many times and caused off-grid accidents because oscillation. SSO become one main problems that restrict development new energy. In this paper, grid-side converters (GSCs) doubly-fed induction generators (DFIGs) under is studied. Firstly, influence mechanism on GSC multipath d...

This paper investigates the impact of doubly-fed induction generator (DFIG) wind farms on system stability in multi-generator power systems with low-frequency oscillations (LFOs). To this end, establishes interconnection model equivalent generators and derives state equation. On basis, an updated equation new integrated is further derived. Then, according to equation, factors that cause changes...

This article presents a perturbation observer–based robust nonlinear damping control (RNDC) scheme for doubly fed induction generator (DFIG)–based wind farm to damp the inter-area oscillations of multi-area power systems. In RNDC scheme, term is introduced describe combined effects nonlinearities, uncertainties, and disturbances systems with farms. The feedback linearization realized reactive l...

With the increasing wind power penetration, farms are directly influencing systems, so need to improve quality of system is an open research topic. A Doubly-Fed Induction Generator (DFIG) often used in systems. However, DFIG has a complex structure and works harsh environments, potential faults may occur. Faults can cause fall into chaotic working state, which harmful phenomenon for DFIG, since...

The major concern in smooth operation of the DFIG wind turbine technology is control of wind turbine generators to ensure stable operation and to avoid sympathetic trips during system imbalances. The operation of the DFIG under different disturbances is analyzed using MATLAB Simulink and the built-in model developed by DIgSILENT in their PowerFactory software. The specific imbalances studied ar...
