Abstract

A stand-alone power supply system based on wind energy is presented in this paper. A permanent magnet synchronous generator (PMSG) is connected to the load through a switched mode rectifier and an inverter. Battery is used as an energy storage device and interfaced to the wind energy system through DC-DC converter. Control strategies are presented to regulate the voltage and frequency of the output ac voltage of an inverter irrespective of variations in the wind speed and load. PWM inverter control is incorporated to balance the line voltages at point of common coupling (PCC) under the condition of unbalanced load. Extensive simulations have been performed using Matlab/Simulink. Simulation results show that the controllers can regulate the voltage and frequency under varying wind speed and load conditions.
