Abstract
Conference Title: 2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA) Conference Start Date: 2014, Dec. 21 Conference End Date: 2014, Dec. 23 Conference Location: Hammamet, Tunisia This article is to study the static stability of Tunisian electrical network face to many current technical constraints to maintain the security of the entire system power. In this context, we present a study based on the modal analysis of the linearized system. This study allows us to determine the optimum location of power regulators PSS injected at the input of voltage regulator AVR based on a matrix called "participation". The regulators method residues perform the calculation of these parameters.
