Estudio de prefactibilidad técnica y económica de la reconfiguración de un sistema de subtransmisión de energía eléctrica para reducción de pérdidas y regulación de voltaje: enfoque en un caso de estudio ecuatoriano

Abstract

This study analyzes the technical and economic feasibility of reconfiguring a subtransmission system, aimed at enhancing system reliability, reducing losses, and maintaining acceptable voltage levels under both normal operating conditions and contingencies. Tools such as DIgSILENT PowerFactory and Python were employed to develop an integrated model capable of evaluating the current system and projecting demand growth scenarios over a 10-year horizon. The methodology involves detailed power flow analysis, demand forecasting, and contingency simulations to assess the impact of subtransmission line outages. In this study, the term "reconfiguration" is broadly applied to include not only topological changes but also actions involving operational adjustments and, in some cases, the construction of new system elements. Based on the results, critical points are identified, and several alternatives are evaluated to select the most viable option in terms of technical and operational impact. Finally, operational and technical benefits are highlighted, justifying the required investment. This approach supports the development of a more reliable and efficient system, prepared to address the sustained growth in demand.
