In recent years, the wind energy conversion system faces significant challenges for stable and secure operations, especially in weak grid due to high penetration of into grid. Doubly fed induction generator (DFIG) is one most popular turbine generators its cost-effective variable speed low-cost partial size power converter. Impedance interaction between series or parallel compensated DFIG cause...

Hybrid power systems have been designed to consist of wind and diesel power plants, as these types of power systems can reduce the harmful effects of conventional diesel-only power plants. Wind power is more commonly used in this set up and preserves the generating margin of doubly fed induction generators (DFIG) under varying wind speeds and changing load conditions, which plays a significant ...

Abstract This paper presents the performance evaluation of Doubly-Fed Induction Generator Using Combined Vector Control and Direct Power Control Method. Combined vector and direct power control (CVDPC) is used for the rotor side converter (RSC) of double-fed induction generators (DFIGs). The control system is according a direct current control by selecting suitable voltage vectors from a switch...

This paper reviews the various control crowbar methods associated with doubly-fed induction generator (DFIG) wind energy system (WES) during power faults.

Wind energy today, has attracted widespread interest from among a variety of sources of renewable energy in the world. Owing to the increasing demand for production of electrical energy for electricity networks by using wind power, it is essential that wind power plants are actively incorporated in the network’s performance using an appropriate control system. In general, these wind power plant...

The increasing size of wind farms requires power system stability analysis including dynamic models of wind Power generation. Nowadays, the most widely used generator type for units above 1MW is the doubly-fed induction machine. The behavior of these machines during grid failure is an important issue. In this paper, a theoretical analysis of the dynamic behavior of the doubly fed induction gene...

In a wind power generator using doubly fed induction generator (DFIG), the three-phase pulse width modulation (PWM) voltage source converter (VSC) is used as grid side converter (GSC) and rotor side converter (RSC). The standard linear control laws proposed for GSC provides not only instablity against comparatively large-signal disturbances, but also the problem of stability due to uncertainty ...

Abstract—In this paper, type-2 fuzzy logic control (T2FLC) and neuro-fuzzy control (NFC) for a doubly fed induction generator (DFIG) based on direct power control (DPC) with a fixed switching frequency is proposed for wind generation application.
