Abstract

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 single machine infinity bus (SMIB). The difference between mechanical power and electrical power is the input to the GAPOD, and the output of GAPOD is connected to UPFC. GA tunes the parameters of POD  ana DCVR by minimizing the error; this error is the difference between mechanical and electrical power. The proposed method is applied to SMIB in MATLAB/Simulink environment, and results compared with Particle Swarm Optimization based multi stage DC voltage controller (PSOMSFDCVR) at different loading conditions.
