<p>Optimal control of any variable speed wind turbine needs maximum power point tracking (MPPT) coupled to doubly fed induction generator (DFIG) for better generation. This paper offers a novel direct servo-speed turbine. latter is based on DFIG optimal hysteresis MPPT inverter current combined with space voltage modulation (SVM) technique, thus providing stable and continuous energy flow...

Abstract This paper proposes a Lithium Titanate battery-based primary frequency regulation strategy for doubly fed induction generators to solve the problems of decrease in power generation efficiency and an increase turbine losses under traditional over-speed load shedding control strategy. A stator voltage orientation-based dual closed-loop vector system is designed PWM rotor converter. grid ...

This paper presents an accurate framework for incorporating the doubly fed induction generator based wind farms in load flow analysis of distribution systems. The proposed model is on equivalent circuit and also takes into consideration voltage dependent reactive power limits associated with generator. In addition, developed approach capable handling a operating either maximum point tracking or...

This paper focuses on PSS/E modeling of wind farms of Doubly-fed Induction Generator (DFIG) type and their impact on issues of power system operation. Since Wind Turbine Generators (WTG) don’t have the same characteristics as synchronous generators, the appropriate modeling of wind farms is essential for transmission system operators to analyze the best options of transmission grid reinforcemen...

Purpose The purpose of this paper is to provide an analysis the performance a new five-phase doubly fed induction generator (DFIG). Design/methodology/approach This presents results research work related DFIG framing, including development analytical model, FEM as well laboratory tests prototype. proposed behavioral level model based on winding function approach. developed was used at design st...

This paper presents Maximum Power Point Tracking (MPPT) controller design of Doubly Fed Induction Generator (DFIG) using Genetic Algorithm (GA). Essential feature of proposed controller is that it is used to trace the maximum power when wind speed is lower than the rated wind speed. Doubly-Fed Induction Generator DFIG has stator terminals are connected directly to the grid. However, the rotor t...
