Combined Facts Devices for Reactive Power Control by Using Optimization Technique

Abstract

Improving the voltage profile and controlling the losses during transmission will be achieve by using FACTS devices. In this effort, two FACTS devices for a better output. The motivation of this work is simulation proram for this thirty-bus system with combined UPFC and TCSC by carrying out using MATLAB. Here, UPFC is used since it has the potential to control real and reactive power and also for reducing the losses in this system. Since, there is a great demand of adequate transmission capacity to maintain the transmission network we use flexible AC transmission system which provides enough transmission capacity and controls the flow of power. The optimisation technique is used in finding the best position of the FACTS devices by improving the voltage magnitude.
