Resumo: | The objective of this research is a preliminary assessment, through load flow studies, the performance of low voltage distribution network in a specific region of the city of Palmas, Tocantins, when connecting Distributed Generation (DG) sources, more specifically, grid-connected photovoltaic systems. Accordingly, with the help of PSAT program, a toolbox of MatLab, it was developed a model of this distribution network so as to reflect the real situation of the residential area of 1106 South Block, city of Palmas TO, taking into account the information and data provided by local power utility and manufacturers. Thus, a model was specified for a grid-connected photovoltaic system, capable of generating only active power, obeying the radiation and temperature profile of the city for a specific day chosen for the study, ie, one with the greatest consumption recorded by the local power utility in year 2012. Tests conducted with the developed model were used to evaluate the behavior of active and reactive power flows without/ with DG in the low voltage network, voltage variations and power factors of the network that are connected grid-connected photovoltaic system. This research has observed that the solar photovoltaic generation offering several advantages both for the concessionaires as well as for consumers where they are installed, as being clean, renewable and with less environmental impact. However, it is important to mention that, despite presenting advantages, only after ANEEL (the National Electrical Energy Agency) published the Normative Nº 482, it started incentives to explore such alternative source. |
