TLDR
In this paper, the authors describe a heuristic method for the reconfiguration of distribution networks in order to reduce their resistive line losses under normal operating conditions, characterized by convergence to the optimum or a near-optimum solution and the independence of the final solution from the initial status of the network switches.Abstract:
The authors describe a heuristic method for the reconfiguration of distribution networks in order to reduce their resistive line losses under normal operating conditions. The proposed approach is characterized by convergence to the optimum or a near-optimum solution and the independence of the final solution from the initial status of the network switches. The methodology has been implemented in a production-grade computer program, DISTOP (Distribution Network Optimization). The compensation-based power flow technique developed at Pacific Gas and Electric Company for the efficient solution of weakly meshed distribution networks is an essential part of this loss reduction methodology. Important implementation aspects of the methodology and the results of its application to several realistic distribution networks are presented. Numerous test results have indicated that the proposed technique is computationally robust and efficient and, hence, suitable for both planning and operations studies. >read more

An immune system approach for power system automation and self healing
Rabie Belkacemi,Ali Feliachi +1 more
TL;DR: In this article, an automation and self healing scheme based on an artificial immune system (AIS) is developed for power systems, which works like a protective layer that strives to eliminate the damages and anomalies to the system while creating an immunity-like for the power systems by remembering the actions taken against a specific anomaly or damage.
