This paper proposes a combination of Genetic Algorithm based Power Oscillation Damping (GAPOD) and DC Voltage Regulator (DCVR) controllers are proposed for Unified Power Flow Controller (UPFC) for the enhancement of dynamic stability of IEEE 30 bus system. The difference between mechanical power and electrical power is the input to the GAPOD, and the output of GAPOD is connected to UPFC one of the input and the input of GADCVR is deviations of capacitor voltage and this output connected to another input of UPFC. GA tunes the parameters of POD and DCVR by minimizing the error; this error is the difference between mechanical and electrical power. The proposed method is applied to IEEE 30 bus system in MATLAB/Simulink environment, and results compared with Genetic Algorithm based Multi Stage Fuzzy DC Voltage Regulator (GAMSFDCVR) and conventional controllers. The results demonstrated that the proposed controller is effectively damping the oscillations.
