چکیده
The main objective of this paper is to investigate the enhancement of damping the power system oscillation via coordinated design of the Power System Stabilizer (PSS) and STATic COMpensator (STATCOM) controllers. The design problem of PSS and STATCOM controllers are formulated as an optimization problem. Using the developed linearized model of a power system equipped with STATCOM-based stabilizer & PSS, the particle swarm optimization (PSO) algorithm is employed to search for optimal controllers parameters. In addition, the paper presents a singular value decomposition (SVD) based approach to asses and measures the controllability of the poorly damped electromechanical modes by different controllers’ inputs. The proposed controllers are evaluated on a single machine infinite bus power system with STATCOM installed. The nonlinear time domain simulation and eigenvalue analysis results show the effectiveness of the coordinated design in damping the power system oscillation.
