The coordination between unified power flow controller (UPFC)‎and power system stabilizer (PSS)‎ for enhancing power system stability

الملخص EN

The main objective of this study is to investigate the enhancement of the power system stability via coordinated design of the Power System Stabilizer (PSS) and mB-based stabilizer of unified power flow controller (UPFC).

The design problem of PSS and mB-based stabilizer are formulated as an optimization problem.

Using the developed linearized model of a power system equipped with UPFC & PSS, the particle swarm optimization (PSO) algorithm is employed to search for optimal controllers parameters..

The proposed controllers are evaluated on a single machine infinite bus power system with UPFC installed.

The nonlinear time domain simulation and eigenvalues analysis results show the effectiveness of the coordinated design in enhancing the power system stability.
