2. 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

3. Network modelling of palm biodiesel plants to supply the isolated electric power systems of Pará state
Despite the great advance brought by the National Interconnected System (NIS), which is able to provide clean hydroelectric power to almost all Brazilian customers, there are still cities supplied by power generated from fossil fuel, which are subsidized by taxes, they are called Isolated Electric Power Systems (IEPS). Pará State, that has 34 cities with IE

4. Algoritmos para o planejamento da operação de sistemas modernos de distribuição de energia elétrica = : Algorithms for operation planning of modern electric distribution power systems / Algorithms for operation planning of modern electric distribution power systems
The distribution system operation planning stage is concerned with the determination of capacitor bank, transformer and voltage regulator settings. This must be accomplished considering active and reactive power injections of distributed generators and at the main substation, as well as physical and regulatory issues in order to improve the network performan

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

8. Monitoramento de temperatura do motor de aerogeradores de pequeno porte utilizando Power Line Communication -PLC
The control system and supervision have been revealed very important in product systems. To guarantee the function with quality, industrial process requires a permanent control being necessary keeping stable some variables. One important factor to point using remote monitoring is the possibility to centralize the control of one process in distinct place, man

10. Sistema inteligente para alocação eficiente de dispositivos indicadores de falta em alimentadores de distribuição / An intelligent system for efficient allocation of fault indicators in distribution feeders
Fault Indicator (FIs) devices have contributed to improve the location of faults on primary feeders, and consequently the reliability of distribution systems. However, one of the main problems facing their installation in a large scale in a distribution system is the lack of efficient methods to analyze big networks and to pinpoint exactly on which buses the

11. Análise de novos sinais para a detecção de ilhamento de geradores síncronos distribuídos / New signals for anti-islanding protection of synchronous distributed generators
Geradores síncronos conectados em redes de distribuição de energia elétrica estão sujeitos a operarem de forma ilhada após a ocorrência de distúrbios na rede elétrica. Ilhamento ocorre quando uma parte da rede de distribuição torna-se eletricamente isolada da fonte de energia principal (subestação), mas continua a ser energizada por geradores di

12. Gerenciamento da oferta e da demanda em micro-sistemas de energia via otimização por enxames de partículas
Intelligent micro-grids, which integrate distributed energy resources with loads, are among the current major tendencies for electric power distribution systems. Distributed resources promote important changes in the operation and management of the distribution system, since they require that the control and the intelligence of the system must be distributed
