TLDR
In this paper, a method for determining a minimal-loss radial configuration for a power distribution network, using an exhaustive search algorithm, is proposed, deriving its efficiency from the use of graph-theoretic techniques involving semi-sparse transformations of a current sensitivity matrix.Abstract:
The authors suggest a method for determining a minimal-loss radial configuration for a power distribution network, using an exhaustive search algorithm. While exhaustive, the method is highly efficient, deriving its efficiency from the use of graph-theoretic techniques involving semi-sparse transformations of a current sensitivity matrix. The algorithm can he applied to networks of moderate size and has advantages over existing algorithms for network reconfiguration in that it guarantees a globally optimal solution (under appropriate modeling assumptions), and is easily extended to take account of phase imbalance and network operation constraints. A 33-bus example is used to demonstrate the operation of the algorithm.read more

Reconfiguration of Power Distribution Systems Considering Reliability and Power Loss
TL;DR: In this article, a power distribution system reconfiguration methodology considering the reliability and the power loss is developed in order to evaluate the reliability at the load points, and an algorithm for finding the minimal cut sets is utilized to find the minimal set of components appearing between the feeder and any particular load point.

Distribution Systems Reconfiguration Based on OPF Using Benders Decomposition
TL;DR: In this paper, a new and efficient methodology for distribution network reconfiguration integrated with optimal power flow (OPF) based on a Benders decomposition approach is presented, which minimizes power losses, load balancing among feeders, and is subject to constraints: capacity limit of branches, minimum and maximum power limits of substations or distributed generators, minimum deviation of bus voltages, and radial optimal operation of networks.

Loss minimization of distribution feeders: optimality and algorithms
TL;DR: Two algorithms are presented: one is based on the uniformly distributed load model and the other on the concentrated current (or power) demand model, based on a concept of 'basic' current profiles of feeder sections and a transformation of the optimization problem.
