| Abstract In Brazil, the demand for the acquisition and installation of photovoltaic systems has grown exponentially and, with that, the importance of studies considering their effects on the distribution grids power flow also grows. Due to the intermittent nature of photovoltaic generation, it is important to approach the analysis in a discrete way, taking into account the changes in the power injections during the studied period. Thus, this article presents the daily analysis of the effects of photovoltaic generation on the distribution system through the computational implementation of a discretized power flow routine. The implemented routine can also analyze the effects of other distributed generations on distribution grids, whether those grids are... |

| ABSTRACT The Market share of electrical vehicles has been rising in the past few years and tends to rise even more. According to the International Energy Agency, an increase of 50% in the number of electrical vehicles is expected. Whilst that increase is beneficial from a greenhouse gases emissions drop point of view, that rise could, on the other hand, represent a major increase in the electrical power consumption. Besides, other problems such as harmonics and overloads could emerge from the massive connection of electrical vehicles to the electrical grid. Therefore, it is necessary to perform studies and simulations in order to estimate those problems and to mitigate the problems related to the inevitable expansion of the electric vehicle fleet in the... |

| ABSTRACT In the search for new options for the establishment of the energy matrix of Brazil, the Grid-Connected Photovoltaic Systems (GCPVS) are configured as an alternative to urban centers, because they allow the power generation at distributed mode, that is, generate energy at the place where it will be consumed and inject the surplus energy into the network. Faced with the prospect of installing Grid-Connected Photovoltaic System, the objective of this research is to characterize this type of photovoltaic system installed in Curitiba, State of Paraná, Brazil. This paper highlights that up to July 2017 the State of Paraná has 1031 GCPVS in operation, which corresponds to 6,6MW, while Curitiba has 204 GCPVS that represents 997.4 kW in operation, 82% of... |

| ABSTRACT The increase in energy demand in Brazil encourages the country to increasingly invest in generation of electric energy, where the demand for other renewable sources increases gradually because they have a lower impact on the environment. The use of Grid-Connected Photovoltaic Systems (GCPVS) is a viable solution for the country, since it presents favorable natural conditions for the use of solar energy. This study approaches the current scenario of three photovoltaic systems installed in Curitiba in 2016 and part of 2017: Green Office (GO) located in Curitiba Campus Downtown, Curitiba Campus Neoville, both of the Federal Technological University of Paraná (UTFPR), as well as a residence. By means of performance parameters, performance analysis of... |
