TL;DR: The results of applications to two real systems show unexpectedly that hourly reconfiguration is not so effective, if compared to a simple maximum or average demand reconfigurations.
Abstract: This paper presents how the application of the minimal loss reconfiguration in distribution networks can help to evaluate online reconfiguration benefits, considering the time varying nature of loads, using daily load profiles in each node of the system. The emphasis in this evaluation is hourly reconfiguration in distribution systems, compared to fixed topologies, considering maximum and average demand of the system. The results of applications to two real systems show unexpectedly that hourly reconfiguration is not so effective, if compared to a simple maximum or average demand reconfiguration. These conclusions are based on the decrease of obtained losses and on the amount of commutations involved in the hourly reconfiguration process.

TL;DR: A two-stage method to co-optimize the repair, reconfiguration, and distributed generation dispatch to maximize the picked-up loads and minimize the repair time for large distribution systems with multiple damages is proposed.
Abstract: This paper proposes a two-stage method for the outage management of power distribution systems. The first stage is to cluster repair tasks of damaged power generation and delivery components based on their distances from the depots (central crew stations) and the availability of resources, to improve the computational efficiency in solving outage management problems for large distribution systems. The second stage is to co-optimize the repair, reconfiguration, and distributed generation dispatch to maximize the picked-up loads and minimize the repair time. The distribution system repair and restoration problem is formulated as a mixed integer linear program, considering constraints of system operation and routing repair crews. Crews are dispatched considering equipment resources, traveling time, and repair time. The proposed method is tested on modified IEEE 34 and 123-bus distribution test systems with multiple damages. The results demonstrate the advantages of co-optimizing repair and restoration.

TL;DR: In this article, a three-phase docking process is described that utilizes both open-and closed-loop techniques, and it has been shown to work with an early version of the system.
Abstract: Chain modular robots form systems with many degrees of freedom which are capable of being reconfigured to form arbitrary chain-based topologies. This reconfiguration requires the detaching of modules from one point in the system and reattaching at another. The internal errors in the system (especially with large numbers of modules) are such that accurate movement of chain ends, required for the attaching of modules, can be extremely difficult. A three-phase docking process is described that utilizes both open- and closed-loop techniques. This process has been shown to work with an early version. Issues raised during this testing have been addressed in a later version. Discussion of these issues, their solutions, and preliminary results of the testing the latest version are given.
