TLDR
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. >read more
