Distribution system reconfiguration for loss reduction: an algorithm based on network partitioning theory

Abstract

The algorithm proposed in this paper provides the facility to achieve online distribution system reconfiguration for loss reduction. Based on partitioning the distribution network into groups of load buses, such that the line section losses between the groups of nodes are minimized, the proposed method overcomes the size restrictions imposed by previously described reconfiguration techniques. By dividing the distribution network into groups of buses, the combinatorial nature of the reconfiguration problem is overcome, while simultaneously minimizing losses. Computer simulations of the proposed method demonstrate the numerous benefits that are offered by the proposed reconfiguration algorithm.
