13. Serviços ancilares através da geração distribuíba : reserva de potência ativa e suporte de reativos / Ancillary services provide by distributed generation : active power reserves and reactive support
In order to set the principles for a future regulatory framework in Brazil which involves the participation of distributed generation (DG) to provide ancillary services; this work presents an analysis developed in three broad areas, technical, economic and regulatory. A specific objective of the project is to make an analysis of the use of the DG for the sup

14. Metodo baseado em logica nebulosa para alocação de geradores distribuidos sob a optica do perfil de tensão / Method based on fuzzy logic for allocating distributed generators from the viewpoint of the voltage profile
This work consists in proposing a methodology based on Fuzzy Logic to obtain an index, which classifies the buses more suitable to install a distributed generator in an electric power distribution system. Themethodologywas developed taking into consideration the difficulty tomaintain a suitable voltage profile in distribution systems, so the methodology resu

15. Solução de problemas de otimização utilizando arquitetura híbrida. / Solution of optimization problems using hybrid architecture.
Electrical power could be considered as one of the economy propulsion vector of a country, assuming extremely important and strategic role because it makes direct influence to the production capacity. The expansion of electrical energy production could not only be done in a short time because constructions in this area take many years and could require more

16. OUTFLOW FORECAST BASED ON ARTIFICIAL NEURAL NETORKS AND WAVELET TRANSFORM / PREVISÃO DE VAZÃO POR REDES NEURAIS ARTIFICIAIS E TRANSFORMADA WAVELET
The hydroelectricity system is responsible for 83.7% of the electric energy generated at Brazil. Therefore, the generation of electric power in Brazil depends basically on the natural flow rates distributed by twelve basins in the country. The quality of prediction of natural flow is of crucial importance for the Brazilian governmental agency, ONS (from the

19. AnÃlise energÃtica experimental e estudo da viabilidade econÃmica de um grupo gerador de 30 kWe A gÃs natural em diferentes nÃveis e tipos de cargas elÃtricas
Due to the lack of investment in the Brazilian electricity sector, together with the increment of the economy, there is a great possibility of new electricity rationing in 2007. This energy shortage imposes that the companies, which do not intend to have a reduction in their production capacity, supply their own electricity. One of the main options is the el

20. COMPUTATIONAL ASPECTS OF MARKET EVALUATION OF THE DYNAMIC SECURITY ON POWER ELECTRICAL SYSTEMS / ASPECTOS COMPUTACIONAIS E DE MERCADO DA AVALIAÇÃO DA SEGURANÇA DINÂMICA DE SISTEMAS ELÉTRICOS DE POTÊNCIA
In this work, different methodologies for the dynamic security assessment of electric energy systems, the calculation of preventive control measures and the quantification of the economic impact of the generation rescheduling, are used. For the dynamic security assessment the following modules have been adopted: initial data processing and generation of the
