1. Analysis of shifting and reduction of the demand peak with the inserting of photovoltaic systems in the Neoville’s Headquarters of Federal University of Technology - Paraná Curitiba Campus
ABSTRACT Photovoltaic solar energy is increasingly present in the urban environment through the distributed generation. This kind of generation is characterized by the installation along the distribution network feeders, in low or medium voltage, and contribute to provide energy near the point of consumption. In this sense, this study aims to analyze the dem

2. 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

3. 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

5. TRANFORMADA WAVELET E REDES NEURAIS ARTIFICIAIS NA ANÁLISE DE SINAIS RELACIONADOS À QUALIDADE DA ENERGIA ELÉTRICA / WAVELET TRANSFORM AND ARTIFICIAL NEURAL NETWORKS IN POWER QUALITY SIGNAL ANALYSIS
This work presents a different method for power quality signal classification using the principal components analysis (PCA) associated to the wavelet transform (WT). The standard deviation of the detail coefficients and the average of the approximation coefficients from WT are combined to extract discriminated characteristics from the disturbances. The PCA w

6. Analise dos sistemas de proteção e controle de instalações industriais com geradores sincronos durante operação ilhada / Protection and control systems analysis of industrial plants with synchronous generators during islanded operation
Modern industrial systems are very sophisticated installations with a high number of automatic processes and capability of isolated (islanded) operation after contingences by using onsite generators composed mainly by synchronous machines and steam turbines. Such installations, in the presence of generators, are generically called autoproducers. Since many o

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

12. Um algoritmo para estimação de estado em alimentadores de distribuição de energia elétrica com base no método da soma de potências
Most algorithms for state estimation based on the classical model are just adequate for use in transmission networks. Few algorithms were developed specifically for distribution systems, probably because of the little amount of data available in real time. Most overhead feeders possess just current and voltage measurements at the middle voltage bus-bar at th
