DESIGN OF STABILIZING SIGNALS BY USING MODEL PREDICTIVE CONTROL

This paper investigates the ability of Model Predictive Control (MPC) in coordinate design of two Power System Stabilizers (PSSs) and a supplementary controller for Static Var Compensators (SVC) to damp the power system inter-area oscillation. For this the parameters of the PSSs and the supplementary controller are determined simultaneously by a method in MPC, known as Generalized Predictive Control (GPC). The numerical results are presented on a 2-area 4-machine system to illustrate the feasibility of GPC algorithm. To show the effectiveness of the designed controllers, a three phase fault is applied at a bus. The simulation study shows that the designed controller by GPC performs well.
