1. Contribuição dos Sistemas Fotovoltaicos Conectados à Rede Elétrica para a Redução de CO2 no Estado do Ceará
Resumo A questão energética tem um significado relevante no contexto da busca do desenvolvimento sustentável, sendo condição essencial para encontrar caminhos alternativos para substituir o uso de combustíveis fósseis. O estado do Ceará possui potencial para o uso de energias renováveis, especialmente a eólica e solar. Este artigo tem como objetivo

2. MODELO PARA A ANÁLISE ECONÔMICA E FINANCEIRA EM PROJETOS PARA GERAÇÃO DISTRIBUÍDA DE ENERGIA COM FONTES ALTERNATIVAS / MODEL FOR THE ECONOMIC AND FINANCIAL ANALYSIS OF DISTRIBUTED ENERGY GENERATION PROJECTS WITH ALTERNATIVE SOURCES
The implementation of distributed generation (DG) offers many benefits to the society, the electrical sector where they operate, and the consumers connected to the network especially due to their electricity self-production. For this case, proponents normally fight against costs estimation problems in projects of DG. In this way, low-cost and quality pre-fea

3. ASPECTOS TÉCNICOS E OPERACIONAIS DO USO DE MICROTURBINAS CONECTADAS AOS SISTMAS ELÉTRICOS PARA GERAÇÃO DISTRIBUÍDA DE ENERGIA / TECHNICAL AND OPERATIONAL ASPECTS OF THE USE OF MICROTURBINES CONNECT TO THE ELECTRICAL SYSTEM FOR DISTRIBUTED ENERGY GENERATION
The considerable increase in energy demand has increased the interest in reducing costs, improving reliability, quality and stability of power generation systems. The connection of distributed generation (DG) can be used as a strategic element to improve the voltage levels in power system. Microturbines (MT) have certain advantages over other models of GD, s

4. Uma contribuição à alocação de geração distribuída, a inserção de PCHs com máquinas síncronas nos sistemas rurais de média tensão
The present work is about an analysis in the domain of distributed generation (DG) allocation in rural distribution systems; the study takes into account the synchronous machines. In such a way, it was possible to research several impacts caused by DG in distribution systems, such as: the rotor angle stability problem under small disturbances; increase of vo

5. 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

6. CONTRIBUTIONS TO STUDY OF WIND FARM CONNECTION TO THE UTILITY / CONTRIBUIÇÕES AO ESTUDO DE CONEXÃO DE GERAÇÃO EÓLICA À REDE ELÉTRICA
Distribution systems have not been designed to receive distributed generation (DG) units. The electric energy injection in these systems is safe and reliable if the characteristics regarding of DG interconnection in distribution power systems are considered: (i) Protection; (ii) Stability; (iii) Electric energy market; (iv) Quality of energy. In this work, a

7. Methodology of prospection and evaluation of pre-viability fast of ditributed generation (DG): eolic and hydraulic case. / Metodologia de prospecção e avaliação de pré-viabilidade expedita de geração distribuída (GD): caso eólico e hidraúlico.
Estudos convencionais de identificacao e de viabilidade de potenciais de producao de energia eletrica eolica e hidroeletrica de pequena escala demandam trabalhos de campo que, muitas vezes, implicam na inviabilidade economica do negocio em funcao dos seus onerosos custos. Alem disso, a execucao desses trabalhos nao assegura ao investidor a recuperacao desses

8. 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
