Implementation of Voltage Stability using Tracking Algorithm in Wind Turbine Connected to the Grid

Abstract

Wind power, the rapid growing source of energy is clean, available freely and has no hazardous gas emission during operation. Many individual wind turbines are being installed collectively and connected to power systems. Intelligent Maximum Power Point Tracking (IMPPT), accepts wind speed and pitch angle as input achieves maximum power using Permanent Magnet Synchronous Generator (PMSG). In PMSG the rotor speed is directly proportional to wind power. The output of PMSG is given to the rectifier, inverter and then connected to the load through the filter. Pulse Width Modulation (PWM) generates switching pulses for the output for reactive power compensation. At different wind speed conditions an IMPPT algorithm is proposed to achieve maximum power output and reduce the operating cost by measuring rotator torque and MPPT. The simulation results are implemented using MATLAB Simulink.
