Abstract

This paper presents enhancement of power system dynamic stability by using unified power flow controller with assuming several real conditions and practical power system constraints. In control method design, we used all four UPFC basic controllers simultaneously with reducing conflict of them by compromising between its control variables. Optimization problem have been used with regarding some constraints of the system and unified power flow controller. Particle swarm optimization algorithm has used to optimize power oscillation damping based on unified power flow controller with an objective function. Simulation results in several multi-machine test power systems demonstrate the capability of applied control system with regarding many constraints and limits of power system and UPFC in different scenarios.
