Expansión óptima de sistemas de transmisión considerando ataques intencionales y estabilidad angular

Abstract

In electrical power systems, one of the main problems is to have a correct transmission system expansion planning (TEP), taking into account intentional attacks that are currently more common because that transmission lines have a very geographic area extensive. An analysis of reinforcement of the power systems (SEP) is framed through an optimization that allows seeing which transmission lines should be increased in the analyzed systems. For this study, an optimization was implemented where it allows seeing the candidate transmission lines with a planning objective of ten years, through optimal flows of DC power where analysis parameters were proposed to only consider active power and modular voltage of 1 p.u on all bars of the systems. The intentional attacks carried out were done randomly in the two systems analyzed, where a contingency index ranking is carried out that allows knowing which of these contingencies can affect the system the most. Finally, an analysis of the stability of the systems was carried out, comparing before, during and after the contingencies carried out, where it was found that by applying the optimizations the systems remain stable despite the intentional attacks carried out.
