TL;DR: In this paper, two feeder reconfiguration algorithms for the purpose of service restoration and load balancing in a real-time operation environment are described, which combine optimization techniques with heuristic rules and fuzzy logic for efficiency and robust performance.
Abstract: This paper describes two feeder reconfiguration algorithms for the purpose of service restoration and load balancing in a real-time operation environment. The developed methodologies combine optimization techniques with heuristic rules and fuzzy logic for efficiency and robust performance. Many of practical operating concerns of feeder reconfiguration and the coordination with other distribution automation applications are also addressed. The developed algorithms have been implemented as a production grade software. Test results on PG&E distribution feeders show that the performance is efficient and robust.

TL;DR: In this paper, a comparison of various methods applied to feeder reconfiguration for loss minimization is presented, and it is shown that linear programming, in the form of transportation algorithms, is not suitable for real-time application to feeders, whereas heuristic approaches, although not optimal, can provide substantial savings if properly formulated and are suited for realtime implementation.
Abstract: The authors present a comparison of various methods applied to feeder reconfiguration for loss minimization. A new linear programming method using transportation techniques and a new heuristic search method are proposed for comparison with a previously developed heuristic technique which was based on an optimal load flow analysis. The methods are compared on simulations of both a small feeder distribution system, and a larger system based on a model of a public utility commission 44 kV distribution system. This study indicates that linear programming, in the form of transportation algorithms, is not suitable for real-time application to feeder reconfiguration, whereas heuristic approaches, although not optimal, can provide substantial savings if properly formulated and are suitable for real-time implementation. >

TL;DR: A scalable and/or reconfigurable true-time-delay analog beamformer system has been proposed in this article, where the number of beams or beam positions that are desired advantageously do not need to be known prior to the design or selection of the beam-former system.
Abstract: A scalable and/or reconfigurable true-time-delay analog beamformer system having a hierarchical distributed control architecture composed of an arbitrary number of reconfigurable and scalable units. The beamformer system may be applied to an antenna array with an arbitrary number of elements in a scalable manner and the configuration of the beamformer system may be implemented so that it is capable of reconfiguration by changing its beam-position mapping, either dynamically or at install-time. The number of beams or beam positions that are desired advantageously do not need to be known prior to the design or selection of the beamformer system.
