A methodology for reclosers allocation in distribution networks

This paper presents a methodology that defines the most suitable configurations to allocate reclosers in power distribution networks. The methodology is composed by two stages. At the first stage, optimal configurations to install reclosers in each feeder are established, considering the improvement promoted in continuity indexes. Each configuration corresponds to a previously fixed number of reclosers and indicates the positions where the devices should be installed. So, through this stage, a list of possible optimal configurations is determined for each feeder. At the second stage a global optimization is carried out, in order to define which configuration should be considered in each feeder from a whole power distribution system, in order to maximize the improvement in terms of continuity and considering the total number of devices available. The developments presented are the initial part of a R&D project in progress with CEMIG-D, a power distribution company from Brazil.
