Planificación de la expansión de los sistemas de transmisión : análisis de la planificación de la expansión de los sistemas de transmisión bajo diferentes objetivos.

Abstract

In this curricular integration work, the Transmission Network Expansion Planning (TNEP) problem is addressed by considering different scenarios, to compare how the benefits change for the actors involved, when different objectives are considered. For this purpose, a TNEP model has been developed based on a mixed integer linear programming evaluated independently in three different objectives: minimization of transmission investment costs, joint minimization of transmission investment and system operation costs, and minimization of CO2 emissions, whose results are analyzed and compared addressing environmental and economic aspects. The model presented employs the simplified DC power flow equations and is implemented using the GAMS (General Algebraic Modeling System) tool; the model is applied in two test systems, the Garver system and the IEEE 24-bus system. The comparative analysis of the results provides a clear view of how the expansion plans change, in infrastructure and benefits when different objectives are considered, so it is essential to consider these aspects when making decisions, since a plan that apparently may be beneficial in one aspect, may be counterproductive in another, and may not yield a common benefit to all actors involved.
