In normal operation, the reconfiguration of distribution network can reduce losses, balance loads and improve quality indicators. The increasing use of remote controlled equipment in power systems leads the development of more efficient techniques for automatic reconfiguration of network, being particularly important in Smart Grid applications.

-This paper shows how a pattern recognition method, the Self-Organizing Maps (SOM) or the Kohonen’s neural network, can be used to construct a Markov model by means of state assignment to a process. This turns possible an easy and fast reliability study of Power Systems. Index Terms -Markov processes, Self-organizing feature maps, State assignment,(More)
This work presents a new methodology for short term loading forecasting whereas the influence of climatic variables (temperature, relative humidity of the air and wind speed) in the consumption behavior of an electrical power distribution system. The proposed methodology involves creating a discrete probability model (Markov chain) from the classification(More)
The need to improve quality and reliability of Power Systems has contributed to the advancement of research on Smart Grids and related topics. Some challenges that motivate the deployment of such researches include the increasing in energy consumption, environmental aspects, the integration of distributed and renewable generation, and new advances in(More)

The benefits and economical results obtained with the utilization of automated systems from some utilities of different countries are showed, indicating their performance. Finally the strategic(More)
The distribution networks have been subjected to increased demand for electricity and the inclusion of distributed generation (DG), which have affected the voltage regulation. In this work, it is proposed a smart distribution transformer, which encompasses an electronic on-load tap changer and a communication system. In addition to the automatic or remote(More)
The parallelism of distribution networks can be used to transfer loads between feeders without the need of disconnection of consumers during the switching. In the context of the Smart Grids, the parallelism of feeders can be used in automatic reconfiguration of networks for the improvement of power quality and voltage levels, and reduction of energy losses.(More)
