The phenomenon of voltage instability and voltage collapse in the power system are particularly severe problems. Many publications analyze and evaluate the phenomena of voltage disturbance, voltage stability, and solutions to improve the power system's voltage stability. In particular, the solution for applying the SVC equipment (Static Var Compensator) to help improve voltage stability has proven effective. However, due to the high cost of the SVC equipment, determining the SVC location to improve the best voltage is essential, especially for the Vietnamese power system. In this paper, the method of applying the saddle point intersection theory to determine SVC's optimal location to help improve the system voltage was presented. The simulation results were performed on UPFLOW software with a test case of the IEEE-300 bus test system.
