Abstract

Power systems are highly nonlinear but we depend to a large extent on linearized methods for analysis and controller design. Aspects of small disturbance stability such as its dependence on parametric change require study of the underlying bifurcation boundaries. Control measures to alleviate problems require sensitivity of margins of stability. In this paper, optimization frameworks developed at Sydney University for computing such boundaries and margins are presented along with a method to coordinate security controls
