VOLTAGE VARIATION CONTROL OF WIND ENERGY USING BUCK BOOST CONVERTER

Abstract

This project explores the application of a Buck-Boost Converter for managing wind energy, specifically aimed at addressing the issue of voltage variations in the output from wind turbines. The objective is to ensure a consistent output voltage during electricity generation, thereby improving the reliability of wind power supply. While there have been notable advancements in wind technology, further enhancements are necessary to optimize power control under diverse loading conditions. The use of a single power MOSFET with a low on-resistance (RDS-ON) is shown to significantly enhance the efficiency of the proposed converter design. This study includes a detailed technical overview, mathematical analysis, and a comparative review of similar systems found in existing literature. A laboratory setup was conducted with a load power rating of 100W at a switching frequency of 50 kHz to validate the performance of the converter. By integrating the Buck-Boost Converter across the DC link, we can maintain a stable voltage supply, which is crucial for consistent electricity distribution under varying environmental conditions. Simulation results were conducted using MATLAB/SIMULINK
