|Voltage Stablization of Wind Energy Conversion System by MPFC Controller
|PWM Techniques;MPPC;Wind Energy Conversion system
|The need to exploit ample renewable energy sources such as wind and solar is growing due to world energy shortage, financial and environmental pollution concerns. Wind energy has made significant progress over the last decades and evolved as one of mature and fastest growing renewable technology due to its nature of intermittent,inexhausitable,adundant and enviormental friendly source of electricity generation. However, the voltage stabilization problem of a wind energy system is dependent on changing wind conditions and varying electric load conditions. Novel techniques are proposed using dynamic stabilization and compensation schemes driven by effective controllers to ensure voltage stabilization under varying wind and electric load conditions. In this dissertation a Modulated Power Filter Compensator controller is used proposed to improve the voltage profile of wind energy conversion system against changing wind and load condition.Different PWM techniques have been proposed for MPFC Controller. The proposed controller is tested on system using Matlab/Simulink environment and it is found that Chaos based SVPWM MPFC controller provides better stabilization of voltage as compared to the SVPWM MPFC controller and PWM based MPFC controller. Harmonic contents in load end voltage and load end current gets reduced in Chaos based MPFC controller as compared to other PWM based MPFC controller.
