1. Efficiency of electricity distribution companies
Abstract Purpose After assessing papers on efficiency, most of the studies available are focused on the analysis of efficiency measures, without providing a deep discussion of the factors that determine efficiency. This study aims to evaluate the efficiency of Brazilian electricity distribution companies based on a structural model that enables the identifi

3. Power Flow Analysis and Self-recovery of Electrical Energy Distribution Network Using Artificial Neural Networks
ABSTRACT A computational model for self-recovery of electricity distribution network was developed to simulate it, emulated by the IEEE 123 node model. The electrical system considered has automatic switches capable of identifying a momentary failure in the line and finding the best reconfiguration for its reclosing. An artificial neural network (ANN), backp

4. Effects of the Photovoltaic Distributed Generation on Electricity Distribution System Voltage - Updated Review
ABSTRACT Concerns about the environment and a growing demand for electricity have led to the intensive search for renewable energy sources. Photovoltaic solar energy, in the form of distributed generation, has shown a very high growth rate to an extent that in some regions it will be adopted on a large scale, thus being responsible for the supply of a signif

5. Distributed generators performance during short-circuits considering fault ride-through requirements / Desempenho de geradores distribuídos durante curtos-circuitos considerando requisitos de suportabilidade a afundamentos de tensão = : Distributed generators performance during short-circuits considering fault ride-through requirements
The increase of distributed generation penetration in distribution systems not only helps to diversify the electrical matrix but also brings both technical and economic benefits. Yet, it also raises worries related to energy supply reliability. For wind power plants into the medium and high voltage networks there are the grid codes for "Fault Ride-Through" w

6. Aplicação de redes inteligentes nas instalações elétricas residenciais / Application of smart grid in residential electrical installations.
Electricity as an energy resource acquired vital importance in modern society because it allows relatively easily meet the demand for their services. Thus the demand for electricity increases with the evolution of populations who benefit from. The electrical system that produces this input is limited in its ability to available resources for generation, tran

11. PLANNING NETWORK DISTRIBUTION OF ELECTRICITY RESTRICTIONS WITH GEOGRAPHICAL AND ELECTRICAL / PLANEJAMENTO DE REDE DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA COM RESTRIÇÕES GEOGRÁFICAS E ELÉTRICAS
This work presents two methods to solve the problem of Electric Distribution Networks (EDN) with geographical and power restrictions. The high cost of the project involving EDN together with lack of efficient methods when working with real applications justifies the development of this research. Taking into account concepts of heuristic and metaheuristic two
