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.

Summary The deployment of smart grid concept at the power distribution level has great potential for improvements to the consumers, e.g., better power quality and higher reliability. The available data allow designing a more efficient control framework aiming to improve operational variables such as power losses and nodal voltage levels. This paper presents a multiobjective control framework for a multifeeder distribution grid, which uses the data gathered from available voltage control devices, power, and current measures, and offline databases. The goal is to determine the best positions of taps in voltage control devices aiming to decrease power losses, switching operations, and fines due to low‐quality steady‐state voltages in a multiobjective problem. Different academic and real distribution networks with multiple feeders are used to test the proposed framework.
