In this paper, an artificial intelligence method particle swarm optimization (PSO) algorithm is presented for determining the optimal PI controller parameters for the indirect control active and reactive power of doubly fed induction generator (DFIG) to ensure a maximum power point tracking of a wind energy conversion system. A digital simulation is used in conjunction with the PSO algorithm to...

The unbalanced voltages cause negative effects on the doubly fed induction generator (DFIG) such as torque pulsation and increased stator current. Based on the symmetrical component theory, the torque pulsation is the consequence of the interaction of stator and rotor currents of different sequences. This paper presents a control technique to reduce the effect of unbalanced voltages on the DFIG...

The increasing penetration of load model in distribution systems may significantly affect voltage stability of the systems, particularly during Low Voltage Ride-Through (LVRT) wind turbine. The main objective of this work is to present the impact of different static and dynamic load models, on the LVRT recovery after disturbances. A component and composite loading structures are considered, com...

-This paper presents the modeling and real-time simulation of a doubly-fed induction generator driven by a wind turbine in large power systems. The Matlab/Simulink/ SimPowerSystems software is used to develop the model for simulation of electromagnetic transients in power systems. The code generated by the Real-Time Workshop of Simulink is linked to the Hypersim digital real-time simulator. A c...
