The Braking Resistor (BR) or Dynamic Brake known as one of the effective practices to enhance the transient stability of synchronous generators and power systems, following a significant disturbance. In this paper, two methods for calculating the value of BR, one by using a one per unit value of BR, and the other one by using calculating criteria or equation to find the value of BR which will give a cost-wise analysis. Also, by using the Thyristor Controlled Braking Resistor (TCBR) with a PID Controller for the control of the insertion of the braking resistor to enhance the transient stability of the proposed power system, the so-called IEEE9Bus System (or Two Machines to Infinite Bus System). Comparison is made in terms of the speed deviation and load angle of the synchronous generators while using the calculated BR and the one per unit BR which will give us a cost-wise analysis when choosing the brake and the effectiveness of the brake to enhance the transient stability of the poposed power system.
