Integrating large amounts of wind power into power systems brings a large influence on the dynamic frequency response characteristic (DFRC). The traditional low-order system frequency response (SFR) model is no longer applicable at the current time. Based on the small signal analysis theory, a set of novel low-order SFR models for doubly-fed induction generator (DFIG) distributed wind power gen...

Penetration of wind power plants (WPPs) in the electric system will complicate load flow analysis. Consequently, traditional algorithm can no longer be used to find solution problem such a system. This paper proposes doubly fed induction generator (DFIG)-based WPP model for analysis The proposed is derived based on formulations WPP—namely, DFIG power, loss, and output formulas. applied various ...

This paper deals with reconfigurable back-to-back converter topology and control orders in Wind Energy Conversion Systems (WECS). A typical WECS with Doubly Fed Induction Generator (DFIG) in balanced conditions is concerned. Based on the classical topology, a fault tolerant converter without any redundancy has been studied. The presented fault tolerant topology allows a “five-leg” structure wit...

This paper proposes the control of a doubly fed induction generator DFIG used in wind turbine energy conversion. The control strategy is based on the linear active disturbance rejection control ADRC to generate the control voltages of the rotor side converter RSC and the grid side converter GSC, due to the changes in control inputs. The ADRC, based on the extended state observer ESO, estimate a...

This paper presents the sizing of a Doubly Fed Induction Generator (DFIG) with power 690.747 kW for coastal area Benin. The proposed DFIG starts from density offshore wind potential Benin obtained at 80 m sea surface to determine generator. Thanks geometrical, electrical and magnetic parameters after sizing, simulation generator operation was done using finite element analysis (FEA). is by runn...

This paper presents the modeling, rapid control prototyping, and hardware-in-the-loop testing for real-time simulation and control of a grid-connected doubly fed induction generator (DFIG) in a laboratory-size wind turbine emulator for wind energy conversion systems. The generator is modeled using the direct-quadrature rotating reference frame circuit along with the aligned stator flux, and the...

The faulttolerant controller is designed to maintain an acceptable level of performance during bearing fa...

Wind Energy Conversion System (WECS) based on Doubly Fed Induction Generator (DFIG) connected to the grid is subjected to high transient currents at rotor side and rise in DC-link voltage during voltage sag at stator/grid side. To secure power system operation wind turbines have to meet grid requirements through the Low voltage ride through (LVRT) capability and contribute to grid voltage contr...

Enhancement of fault ride-through (FRT) capability and subsequent improvement of rotor speed stability of wind farms equipped with doubly fed induction generator (DFIG) is the objective of this paper. The objective is achieved by employing a novel FRT scheme with suitable control strategy. The proposed FRT scheme, which is connected between the rotor circuit and dc link capacitor in parallel wi...
