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...

Energy is one of the most prominent factors in shaping the civilization of today. Under consideration for nonconventional energy source wind energy has turned out to be a leading source of energy. In recent years there has been a significant global commitment to develop a clean and economical alternative sustainable power source especially from wind. In this field of development wound rotor ind...

This paper presents a dynamic modeling and control of doubly fed induction-generator (DFIG) based variable speed wind-turbine. The dynamic model of DFIG is incorporated with all system components which provide simple design and controls. The penetration of wind power is increasing into electrical networks, which necessitates more comprehensive studies to recognize the interaction between the wi...

This paper discuss the configuration, operation and power flow control strategies of a doubly fed induction generator (DFIG) with back-to-back PWM converter for variable speed wind turbines. The mathematical model of the DFIG is taken as appropriate d-q reference frame and their performances are in terms of stator currents references tracking. In order to control the power flow of the network, ...

The wind turbine based on the doubly-fed induction generator (DFIG) plays an increasingly important role in power generation. This is thanks to the benefits of these generators compared to other machines. In this paper, we present a new control strategy that limits variations and the transient overshoots in the DC bus voltage, which cause problems and sometimes leads to destruction of converter...

In this paper, a grid connected wind power generation scheme using a doubly fed induction generator ( DFIG) is studied. The aims of this paper are: The modelling and simulation of the operating in two quadrants (torque-speed ) of a DFIG, the analysis employs a stator flux vector control algorithm to control rotor current, the system enables optimal speed tracking for maximum energy capture from...
