Abstract

This paper aims to present a preliminary study of the behavior of a distribution network with the penetration of grid-connected photovoltaic (PV) system. The work used measurements and data from an area of Palmas, the capital of Tocantins state, Brazil, which is attended by the power utility CELTINS. Three cases were analyzed here: (1) at a given daytime with the original distribution system, (2) at the same time with part of the distribution grid supplied by grid-connected PV systems, and (3) at a given nighttime. All the simulations were performed with PSAT software.
