An Integrated System for Efficient Management of Distribution Networks: The System's Architecture and the Telecommunication Infrastructure
2006
Modern distribution systems must keep up with high power quality standards due to the new regulations of the European Community and of the different national legislations. Efficient faults management is one of the basic tasks utilities must accomplish and this objective can be attained if and only if automation is present and efficient diagnostic procedures have been implemented in the centralized or distributed units all over the network. In this paper, the architecture of an integrated system for management of modern distribution systems is presented. The system includes routines for normal on-line optimal operation of distribution systems and for outage management, the latter including f…
Service restoration in compensated distribution networks using a hybrid genetic algorithm
1998
In this paper a genetic algorithm (GA) based approach to the service restoration (SR) problem in automated distribution networks is presented. Normal operation within the network comprises both automatic reconfiguration and compensation so as to reduce power losses, allow load balancing and improve the voltage profile. In the restorative state, the reconfiguration is performed together with compensation, taking mainly into account the load supply requirement and secondarily, the losses reduction requirement. After a general discussion on the restoration problem together with a short review of recent papers on the topic, a solution strategy is proposed. Then, a short account about classical …
Evolving non-dominated solutions in multiobjective service restoration for automated distribution networks
2001
Abstract The problem here dealt with is that of Service Restoration (SR) in automated distribution networks. In such networks, configuration and compensation level as well as loads insertion status can be remotely controlled. The considered SR problem should be handled using Multiobjective Optimization, MO, techniques since its solution requires a compromise between different criteria. In the adopted formulation, these criteria are the supply of the highest number of loads and the minimum power losses. The Authors propose a new MO approach, the Non-dominated Sorting Fuzzy Evolution Strategy, NS_FES, which uses part of the Non-dominated Sorting Genetic Algorithm, NSGA, proposed by K. Deb. Th…
