Abstract

Flexible alternating current transmission system (FACTS) components are used to utilize the electrical transmission lines at their optimum capacity. The best way to achieve this optimization is to manage the active and reactive power flows. A unified power flow controller (UPFC) is one of the most significant devices developed for the effective control of power flows. Although conventional UPFC structures can be used to achieve this process, the expansion of power systems has led to the necessity of developing various UPFC devices. This paper focuses on an advanced real time control approach of UPFC for dynamic voltage regulation. The developed model is incorporated in the Gauss-Seidel (GS) power flow algorithm and the proposed method is validated on the IEEE-30 bus system that is designed under MATLAB/Simulink platform. As the proposed method was validated by comparing with the normal operating conditions, advantages were observed on two cases. In the first case, a generator outage is applied to system to observe behavior of proposed model in power loss conditions. In the second case, line fault conditions were used for observation. The results from testing the model for both cases prove that the approach has positive effects on dynamic power systems.
