This paper presents a framework for minimizing the average interruption frequency in radial Distribution Systems with uniformly distributed loads. Here, the position of the reclosers has been modeled using a linear approximation. The objective of this paper is to minimize the average interruption frequency per installed power. According to the current electric regulation in Chile, this index is the metric used to regulate and classify the performance of utilities. In the analysis a novel concept of Distance Factor between the main feeder and a branch feeder was introduced. This concept can be utilized as a theoretical limit for the number of switches to install on the main feeder. In addition, based upon the service history of the line, the distance factor determines if a certain line must be economically assessed like a new feeder so that the aforementioned performance index of average interruption frequency per installed power is minimized.

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.
