13. Impactos causados pela universalização do acesso e uso da energia elétrica
Public electric utilities have legal and contractual obligation to supply service to the market of their concession areas, without customer discrimination. New connections used to be accomplished partly with financial support of interested consumers, and the amount of investment of the distribution companies were established in regulations. This practice mad

14. Device for monitoring, registering and analysis of electric power supply continuity indicators / Dispositivo para monitoramento, registro e análise dos indicadores de continuidade no fornecimento da energia elétrica
In the last few years, electric power quality monitoring has been object of attention of electric utilities, in order to meet rising consumer expectations and growing demand. Among the quality parameters, electric power continuity stands out, because it affects productive processes and leads to consumer dissatisfaction. The aim of this paper is to present th

15. ANALYSIS OF THE TRUSTWORTHINESS IN NETS OF DISTRIBUTION RADIAL: RECONFIGURATION AND ALOCATION OF DISTRIBUTED GENERATION / Análise da Cconfiabilidade em Redes de Distribuição Radiais: Reconfiguração e Alocação de Geração Distribuída
The distribution utilities must satisfy two concurrent objectives during planning process of the electric network: minimization of the investment cost and the satisfaction of reliability targets. An alternative to satisfy these objectives is to include low cost alternatives in the planning process. One of these alternatives is the reconfiguration of the dist

16. ALGORITHM DEVELOPMENT FOR THE RELIABILITY OPTIMIZATION ON DISTRIBUTION NETWORKS / DESENVOLVIMENTO DE ALGORITMOS PARA OTIMIZAÇÃO DA CONFIABILIDADE DE REDES DE DISTRIBUIÇÃO
New regulations of the electricity sector have requested greater efficiency from the power utilities in the performance of their distribution systems, requiring more rigorous quality and continuity energy levels. This work has the purpose of stating the best way to model the integer indicators of reliability for electric systems, financial resources and mate

17. Restabelecimento de energia considerando todas as barras e chaves de um sistema de distribuição real / Energy restoration for real distribution systems considering all their buses and switches
This work investigates methodologies to automatically obtain energy restoration plans in distribution systems, involving multiple objectives that are conflicting. The reduction energy interruption indices is a permanent objective of the distribution companies in order to improve power supply. Interruptions may be carried out for maintenance or may occur due

18. DETERMINAÇÃO DO VALOR DA CONFIABILIDADE EM SISTEMAS COMPOSTOS DE GERAÇÃO E TRANSMISSÃO / EVALUATION OF RELIABILITY WORTH IN COMPOSITE GENERATION AND TRANSMISSION SYSTEMS
This work presents a new methodology to evaluate reliability índices in composite generation and transmission systems. Through this new approach is possible to achieve an accurate estimate of the reliability worth of power systems. The modeling flexibility and simulation efficiency are basic features of the proposed approach. Moreover, it is introduced a ne
