Análisis técnico y económico para la incorporación de facts en sistemas de potencia

Abstract

This article shows a methodology for the technical and economic analysis of the incorporation of Facts devices in electrical power systems. The methodology proposed consists of a deterministic stage and a stochastic stage which involve aspects of technical and economic feasibility, respectively. The first stage is based on a non-linear binary mixed programming model developed at AMPL in order to minimize generation of safety given the location of a Facts device. The second stage employs an energetic model based on a stochastic dynamic dual programming (SDDP) which determines the cost-benefit ratios of the incorporation of Facts for different hydrothermal series. In order to illustrate the applicability of the methodology proposed, a case study is shown in the Colombian electrical system, taking into account the incorporation of a Statcom in the Atlantic Coast. Additionally, it is shown that the solution proposed resolves oscillatory instability problems of power, identified in minimum generation scenarios before critical contingencies.
