Output voltage control scheme for standalone wind energy system

This paper presents output voltage control scheme for standalone wind energy systems using self excited induction generator. Nowadays the energy need is depend upon conventional sources but the disadvantage of conventional sources are limited availability and high cost. So the use of non conventional sources must be increased as it is freely available in more amounts. One of the available source is wind energy Nowadays wind energy can be used for grid connected and standalone load demands. The wind nature is unreliable it is not constant so for backup storage device lead acid battery is used. In existing system the MPPT technique is without battery charging mode control has been implemented independently for standalone wind energy applications. As the wind nature is uncertain so we get variable output. As we fed wind output to the buck converter then harmonics are generated. In proposed system this can be accomplished by maximum power point tracking with battery backup when the wind power is not available. For meeting the requirements of 3 KW standalone dc load 4 KW wind battery hybrid system is used. This paper presents a wind energy control with buck converter. By using MATLAB/SIMULINK proposed system is modelled.
