Evaluación mediante enumeración de estados de la confiabilidad del Sistema Interconectado del Norte Grande de Chile (SING).

This paper presents a reliability evaluation of the Chilean SING* by means of an analytical and probabilistic method for the enumeration of states, which permits to determine the unavailability index and the associated overcharge factor. This evaluation allows a comparative analysis between the unavailability index and the associated overcharge factor, the CNE**, provides in its technical reports of local the nodal price. Hereby, the proposed results suggest a solution for continuous observations made by SING electric companies in the technical reports of nodal price, with respect to the criteria used for modeling and determining the unavailability of transmition and associated overcharge factor. The reliability evaluation is made considering generation and transmission facilities. * SING: Northern Interconnected System: Transmission system of high voltage electricity in northern Chile. ** CNE: National Energy Commission: Chilean government agency that oversees the transmission systems of electric power.
