PEREZ-LONDONO, Sandra M.; OLIVAR-TOST, Gerard  e  MORA-FLOREZ, Juan J.. Voltage stability indices - A review and a new classification. Ing. compet. [online]. 2014, vol.16, n.2, pp.115-130. ISSN 0123-3033.

This paper is oriented to present a review of the main approaches commonly used to obtain voltage stability indices in electric power systems. Starting from classifications previously presented, the authors propose a complete review including several subcategories, which help to have a better understanding of these approaches. As strategy to adequately present this research, a chronologically ordered description and a classification of the most relevant characteristics of these proposals, which are aimed to obtain the voltage stability indexes in a time period from 1986 to 2012, is detailed analyzed. The considered classification criterion is related to the information requirements of each one of the reviewed approaches. Additionally, an analysis and a discussion of the evolution of the indexes proposals considering the new available metering equipment are developed. Finally, this review is useful as a reference for discussions related to methodologies associated to voltage stability indexes for electric power systems
