Martha Galaz was born in Hermosillo, Mexico. She obtained his B.Sc. in Industrial and Electronic Engineering from the Hermosillo Technological Institute, Mexico, and she received the M.Sc. degree in Electronics and Telecommunications from the Center for Scientific Research and Higher Education of Ensenada (CICESE), Mexico. Currently she is a Ph.D. student at the Laboratoire de Signaux et Systemes (SUPELEC) in France. Her main research interests are in the fields of nonlinear sytems, power system stability and control and hamiltonian systems.

N2 - In this paper we discuss the estimation of the domain of attraction of equilibria in power systems and propose a new passivity-based controller design methodology for excitation control of synchronous generators. The methodology goes beyond the widely popular damping injection (LgV) schemes, to actually shape the total energy function via modification of the energy transfer between the mechanical and electrical components of the system. Applying the procedure it is shown that a, properly tuned, linear state feedback enlarges both the estimates and the actual domain of attraction, thus increasing critical clearing time for faults. This is illustrated in two case studies, including a benchmark comparison with the classical control scheme.
