Abstract
This thesis presents new technique for controlling power flow to stabilize power systems including wind energy farms. Variable Frequency Transformer (VFT) consider one of the important and new applications of slip ring induction machine. This technique can be implemented to stabilize unique and different frequencies electric power systems. Also, it can be applied with wind energy farms to improve its characteristics and performances
