The New Planning of Voltage Stability in the Restructured Power System by using Teaching and Learning Algorithm

Because of the complexity of the restructured power system, voltage stability is very important in order to review and provide the appropriate solution to keep the system in a steady state after any disturbance and be able to suggest and run the best possible solution for each disturbance .in this case, The voltage profiles stay in the range of its own allowable variation. first of all, The methods of determining the voltage profile and conceptions of disturbance in the restructured power system is described. Then by learning how to get the optimal point and optimization algorithms conclude that If the voltage profile is calculated by using teaching and learning algorithms and load flow is computed by Newton Raphson, then we have gotten the optimal point. Hence, The independent operator of restructured power system can implement optimal points in the network by using the flexible transmission systems.
