Description
Summary:This article demonstrates the basic module, steady state operation, mathematical analysis, and current injection modeling of the DPFC for two area. The purpose of the work reported in this article was to design an oscillation damping controller for DPFC to damp low frequency electromechanical oscillations. The optimal design problem is formulated as an optimization problem, and particle swarm optimization is employed to search for the damping controller parameters. Results demonstrate that DPFC with the proposed model can more effectively improve the dynamic stability and enhance the transient stability of power system compared to the genetic algorithm based damping controllers. The r and γ are relative magnitude and phase angle of DPFC controller. Moreover, the results show that the γ based controller is superior to the r based controller.
