    Resumen

    In this paper, normalized or per unit indices for voltage stability analysis in power systems are proposed. The indices are simple and designed based on reactive power reserves and system loadability margins. The methodology presented with the proposed indices makes it possible to combine the loadability margin evolution and reactive power reserves. The method is particularly useful or beneficial for analysts and operators, since it helps to properly interpret if the presence of reactive power reserve is a guarantee of the stability of voltage in a given location of the power system. The indices were successfully applied, exposing similar trends for an IEEE small network, which is widely known, and for a network having a large number of busbars and generators. On the other hand, through a basic architecture proposed for the integration of information technologies, the convenience of indices usage for modern applications of Synchrophasors and Situational Awareness has been pointed out, in which operators and analysts may count on accurate information about the evolution of the power system and to successfully conceive solutions.
