H∞ loop shaping based robust power system stabilizer for multi machine power system

Abstract

The dynamics of a multi machine power system are both nonlinear and interconnected. The equilibrium of such a system is typically unknown and uncertain, and the controllers within are also subject to physical limitations. Based on the latest development of nonlinear H∞ robust control theory, a control design is applied to stabilize the linearized uncertain system using Glover-McFarlane's loop shaping design procedure for IEEE ten machine 39 bus system. Guidance for setting the feedback configuration for loop shaping and synthesis are presented. The results of simulation studies are presented.
