This study presents fuzzy-proportional–integral (PI)-based sensorless frequency and voltage control strategy for doubly fed induction generator connected to a dc microgrid system. A significant reduction of the costs can be achieved by this topology because only a single dc/ac converter and a diode rectifier are required instead of the traditional back-to-back converter topology. To improve the performance...
In order to integrate different distributed generations (DGs) into a microgrid connected to a weak distribution grid, this paper proposes local controllers based in fuzzy logic. The integration of the DGs is achieved through the ≪plug and play≫ procedure. The understudy microgrid includes an hybrid fuel cell-battery system and a Doubly Fed Induction Generator (DFIG). Through the proposed controllers...
This paper focuses on the implementation of the TS (Tagaki-Sugino) fuzzy controller for the active power and the DC capacitor voltage control of the doubly fed induction generator (DFIG) based wind generator. DFIG system is represented by a third-order model where electromagnetic transients of the stator are neglected. The effectiveness of the TS-fuzzy controller on the rotor speed oscillations and...
